Description
The 6A Digital Pico DLynxTM power modules are non-isolated dc-dc converters that deliver up to 6A of output
current. These modules operate over a wide range of input voltage (VIN = 3Vdc-14.4Vdc) and provide a precisely
regulated output voltage from 0.45Vdc to 5.5Vdc, programmable via an external resistor and further adjustable
through PMBus. Features include a digital interface using the PMBus protocol, remote On/Off, adjustable output
voltage, over current and overtemperature protection. The PMBus interface supports a range of commands to control
and monitor the module. The Tunable LoopTM feature allows the user to optimize the dynamic response of the
converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

Design Considerations
Input Filtering
The 6A Digital Pico DLynxTM module should be
connected to a low ac-impedance source. A highly
inductive source can affect the stability of the module.
An input capacitance must be placed directly adjacent
to the input pin of the module, to minimize input ripple
voltage and ensure module stability.

Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards,
i.e., UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN
EN 60950-1:2006 + A11 (VDE0805 Teil 1 + A11):2009-

For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all
inputs are ELV.
Output Filtering
These modules are designed for low output ripple
voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 22 µF ceramic
capacitors at the output of the module. However,
additional output filtering may be required by the system
designer for a number of reasons. First, there may be a
need to further reduce the output ripple and noise of the
module. Second, the dynamic response characteristics
may need to be customized to a particular load step
change.
The input to these units is to be provided with a fuse
with a maximum rating of TBD in the positive input lead.
To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance
at the output can be used. Low ESR polymer and
ceramic capacitors are recommended to improve the
dynamic response of the module. Figure 38 provides
output ripple information for different external
capacitance values at various Vo and a full load current
of 6A. For stable operation of the module, limit the
capacitance to less than the maximum output
capacitance as specified in the electrical specification
table. Optimal performance of the module can be

logic High and ON during logic Low. The On/Off signal
should be always referenced to ground. For either
On/Off logic option, leaving the On/Off pin disconnected
will turn the module ON when input voltage is present.

Figure 40. Circuit configuration for using negative
On/Off logic.
Monotonic Start-up and Shutdown
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 39. When the
external transistor Q2 is in the OFF state, the internal
transistor Q1 is turned ON, and the internal PWM
#Enable signal is pulled low causing the module to be
ON. When transistor Q2 is turned ON, the On/Off pin is
pulled low and the module is OFF. A suggested value
for Rpullup is 20kΩ.
The module has monotonic start-up and shutdown
behavior for any combination of rated input voltage,
output current and operating temperature range.
Startup into Pre-biased Output
The module can start into a prebiased output as long as
the prebias voltage is 0.5V less than the set output
voltage.
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 40. The On/Off pin should
be pulled high with an external pull-up resistor
(suggested value for the 3V to 14V input range is
20Kohms). When transistor Q2 is in the OFF state, the
On/Off pin is pulled high, transistor Q1 is turned ON and
the module is OFF. To turn the module ON, Q2 is turned
ON pulling the On/Off pin low, turning transistor Q1 OFF
resulting in the PWM Enable pin going high.
Analog Output Voltage Programming
The output voltage of the module is programmable to
any voltage from 0.6dc to 5.5Vdc by connecting a
resistor between the Trim and SIG_GND pins of the
module. Certain restrictions apply on the output voltage
set point depending on the input voltage. These are
shown in the Output Voltage vs. Input Voltage Set Point
Area plot in Fig. 41. The Upper Limit curve shows that
for output voltages lower than 1V, the input voltage must
be lower than the maximum of 14.4V. The Lower Limit
curve shows that for output voltages higher than 0.6V,
the input voltage needs to be larger than the minimum of
3V.

The power module has a Remote Sense feature to

fault (see the description of the PMBus command
VOUT_UV_FAULT_RESPONSE for additional
information).
Output Voltage Sequencing
The power module includes a sequencing feature, EZ-
SEQUENCE that enables users to implement various
types of output voltage sequencing in their applications.
This is accomplished via an additional sequencing pin.
When not using the sequencing feature, leave it
unconnected.
Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current limiting
continuously. At the point of current-limit inception, the
unit enters hiccup mode. The unit operates normally
once the output current is brought back into its specified
range.
The voltage applied to the SEQ pin should be scaled
down by the same ratio as used to scale the output
voltage down to the reference voltage of the module.
This is accomplished by an external resistive divider
connected across the sequencing voltage before it is fed
to the SEQ pin as shown in Fig. 44. In addition, a small
capacitor (suggested value 100pF) should be connected
across the lower resistor R1.
Digital Adjustable Overcurrent Warning
Please see the Digital Feature Descriptions section.
Overtemperature Protection
For all DLynx modules, the minimum recommended
delay between the ON/OFF signal and the sequencing
signal is 10ms to ensure that the module output is
ramped up according to the sequencing signal. This
ensures that the module soft-start routine is completed
before the sequencing signal is allowed to ramp up.
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shut down if the overtemperature threshold of
150oC(typ) is exceeded at the thermal reference point
Tref .Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.

Digitally Adjustable Input Undervoltage
Lockout
When the scaled down sequencing voltage is applied to
the SEQ pin, the output voltage tracks this voltage until
the output reaches the set-point voltage. The final value
of the sequencing voltage must be set higher than the
set-point voltage of the module. The output voltage
follows the sequencing voltage on a one-to-one basis.
By connecting multiple modules together, multiple
modules can track their output voltages to the voltage
applied on the SEQ pin.
Please see the Digital Feature Descriptions section.
Digitally Adjustable Power Good Thresholds
Please see the Digital Feature Descriptions section.
To initiate simultaneous shutdown of the modules, the
SEQ pin voltage is lowered in a controlled manner. The
output voltage of the modules tracks the voltages below
their set-point voltages on a one-to-one basis. A valid
input voltage must be maintained until the tracking and
output voltages reach ground potential.
Note that in all digital DLynx series of modules, the
PMBus Output Undervoltage Fault will be tripped when
sequencing is employed. This will be detected using the
STATUS_WORD and STATUS_VOUT PMBus
commands. In addition, the SMBALERT# signal will be
asserted low as occurs for all faults and warnings. To
avoid the module shutting down due to the Output
Undervoltage Fault, the module must be set to continue
operation without interruption as the response to this

Synchronization
The module switching frequency can be synchronized to
a signal with an external frequency within a specified
range. Synchronization can be done by using the
external signal applied to the SYNC pin of the module as
shown in Fig. 45, with the converter being synchronized
by the rising edge of the external signal. The Electrical
Specifications table specifies the requirements of the
external SYNC signal. If the SYNC pin is not used, the
module should free run at the default switching
frequency. If synchronization is not being used,
connect the SYNC pin to GND.
noise (see Figure 38) and to reduce output voltage
deviations from the steady-state value in the presence of
dynamic load current changes. Adding external
capacitance however affects the voltage control loop of
the module, typically causing the loop to slow down with
sluggish response. Larger values of external
capacitance could also cause the module to become
unstable.
The Tunable LoopTM allows the user to externally adjust
the voltage control loop to match the filter network
connected to the output of the module. The Tunable
LoopTM is implemented by connecting a series R-C
between the VS+ and TRIM pins of the module, as
shown in Fig. 47. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.

PMBus Interface Capability
The 6A Digital Pico DLynxTM power modules have a
PMBus interface that supports both communication and
control. The PMBus Power Management Protocol
Specification can be obtained from www.pmbus.org. The
modules support a subset of version 1.1 of the
specification (see Table 6 for a list of the specific
commands supported). Most module parameters can be
programmed using PMBus and stored as defaults for
later use.

All communication over the module PMBus interface
must support the Packet Error Checking (PEC) scheme.
The PMBus master must generate the correct PEC byte
for all transactions, and check the PEC byte returned by
the module.
The user must know which I2C addresses are reserved
in a system for special functions and set the address of
the module to avoid interfering with other system
operations. Both 100kHz and 400kHz bus speeds are
supported by the module. Connection for the PMBus
interface should follow the High Power DC specifications
given in section 3.1.3 in the SMBus specification V2.0
for the 400kHz bus speed or the Low Power DC
specifications in section 3.1.2. The complete SMBus
specification is available from the SMBus web site,
smbus.org.
The module also supports the SMBALERT response
protocol whereby the module can alert the bus master if
it wants to talk. For more information on the SMBus alert
response protocol, see the System Management Bus
(SMBus) specification.
The module has non-volatile memory that is used to
store configuration settings. Not all settings programmed
into the device are automatically saved into this non-
volatile memory, only those specifically identified as
capable of being stored can be saved (see Table 6 for
which command parameters can be saved to non-
volatile storage).
PMBus Data Format
ADDR1
ADDR0
For commands that set thresholds, voltages or report
such quantities, the module supports the Linear data
format among the three data formats supported by
PMBus. The Linear Data Format is a two byte value with
an 11-bit, twos complement mantissa and a 5-bit, twos
complement exponent. The format of the two data bytes
is shown below:

(0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 40 in decimal) are reserved
according to the SMBus specifications and may not be
useable. The address is set in the form of two octal (0 to

The VOUT_SCALE_LOOP parameter is important for a
number of PMBus commands related to output voltage
trimming, margining, over/under voltage protection and
the PGOOD thresholds. The output voltage of the
module is set as the combination of the voltage divider
formed by RTrim and a 20k upper divider resistor
inside the module, and the internal reference voltage of
the module. The reference voltage VREF is nominally set
at 600mV, and the output regulation voltage is then
given by

Hence the module output voltage is dependent on the

The VOUT_SCALE_LOOP parameter is specified using
the Linear format and two bytes. The upper five bits
[7:3] of the high byte are used to set the exponent which
is fixed at 9 (decimal). The remaining three bits of the
high byte [2:0] and the eight bits of the lower byte are
used for the mantissa. The default value of the mantissa
is 00100000000 corresponding to 256 (decimal),
corresponding to a divider ratio of 0.5. The maximum
value of the mantissa is 512 corresponding to a divider
ratio of 1. Note that the resolution of the
PMBus Adjustable Soft Start Rise Time
The soft start rise time can be adjusted in the module via
PMBus. When setting this parameter, make sure that
the charging current for output capacitors can be
delivered by the module in addition to any load current
to avoid nuisance tripping of the overcurrent protection
circuitry during startup. The TON_RISE command sets
the rise time in ms, and allows choosing soft start times
between 600ʅs and 9ms, with possible values listed in
Table 5. Note that the exponent is fixed at -4 (decimal)
and the upper two bits of the mantissa are also fixed at
0.
VOUT_SCALE_LOOP command is 0.2%.
When PMBus commands are used to trim or margin the
output voltage, the value of VREF is what is changed
inside the module, which in turn changes the regulated
output voltage of the module.
The nominal output voltage of the module can be
adjusted with a minimum step size of 0.4% over a ±25%
range from nominal using the VOUT_TRIM command
over the PMBus.
The VOUT_TRIM command is used to apply a fixed
offset voltage to the output voltage command value

at 0 while the lower five bits are programmable with a
default value of TBD (decimal). The resolution of this
warning limit is 500mA. The value of the
IOUT_OC_WARN_LIMIT can be stored to non-volatile
memory using the STORE_DEFAULT_ALL command.
VOUT(offset) = VOUT _TRIM × 2−10
This offset voltage is added to the voltage set through
the divider ratio and nominal VREF to produce the
trimmed output voltage. The valid range in twos
complement for this command is 4000h to 3999h.
The high order two bits of the high byte must both be
either 0 or 1. If a value outside of the +/-25% adjustment
range is given with this command, the module will set its
output voltage to the nominal value (as if VOUT_TRIM
had been set to 0), assert SMBALRT#, set the CML bit
in STATUS_BYTE and the invalid data bit in
Temperature Status via PMBus
The module can provide information related to
temperature of the module through the
STATUS_TEMPERATURE command. The command
returns information about whether the pre-set over
temperature fault threshold and/or the warning threshold
have been exceeded.
PMBus Adjustable Output Over and Under
Voltage Protection
STATUS_CML.
The module has output over and under voltage
protection capability. The PMBus command
Output Voltage Margining Using the PMBus
The module can also have its output voltage margined
via PMBus commands. The command
VOUT_OV_FAULT_LIMIT is used to set the output over
voltage threshold from four possible values: 108%,
110%, 112% or 115% of the commanded output
voltage. The command VOUT_UV_FAULT_LIMIT sets
the threshold that causes an output under voltage fault
and can also be selected from four possible values:
92%, 90%, 88% or 85%. The default values are 112%
and 88% of commanded output voltage. Both
commands use two data bytes formatted as twos
complement binary integers. The Linear mode is used
with the exponent fixed to 10 (decimal) and the
effective over or under voltage trip points given by:
VOUT_MARGIN_HIGH sets the margin high voltage,
while the command VOUT_MARGIN_LOW sets the
margin low voltage. Both the VOUT_MARGIN_HIGH
and VOUT_MARGIN_LOW commands use the Linear
mode with the exponent fixed at 10 (decimal). Two
bytes are used for the mantissa with the upper bit [7] of
the high byte fixed at 0. The actual margined output
voltage is a combination of the VOUT_MARGIN_HIGH
or VOUT_MARGIN_LOW and the VOUT_TRIM values
as shown below.
VOUT (OV _ REQ) = (VOUT _ OV _ FAULT _ LIMIT) × 2−10
VOUT (UV _ REQ) = (VOUT _UV _ FAULT _ LIMIT) × 2−10
VOUT(MH)
=
(VOUT_ MARGIN_ HIGH+VOUT_TRIM)×2−10
VOUT(ML)
=
(VOUT_ MARGIN_ LOW +VOUT_TRIM)× 2−10
Note that the sum of the margin and trim voltages
cannot be outside the ±25% window around the nominal
output voltage. The data associated with
VOUT_MARGIN_HIGH and VOUT_MARGIN_LOW can
be stored to non-volatile memory using the
STORE_DEFAULT_ALL command.
Values within the supported range for over and
undervoltage detection thresholds will be set to the
nearest fixed percentage. Note that the correct value for
VOUT_SCALE_LOOP must be set in the module for the
correct over or under voltage trip points to be calculated.
In addition to adjustable output voltage protection, the
6A Digital Pico DLynxTM module can also be
programmed for the response to the fault. The
VOUT_OV_FAULT RESPONSE and
VOUT_UV_FAULT_RESPONSE commands specify the
response to the fault. Both these commands use a
single data byte with the possible options as shown
below.
The module is commanded to go to the margined high
or low voltages using the OPERATION command. Bits
[5:2] are used to enable margining as follows:
00XX : Margin Off
0101 : Margin Low (Ignore Fault)
0110 : Margin Low (Act on Fault)
1001 : Margin High (Ignore Fault)
1010 : Margin High (Act on Fault)
1. Continue operation without interruption (Bits
[7:6] = 00, Bits [5:3] = xxx)
2. Continue for four switching cycles and then
shut down if the fault is still present, followed by
no restart or continuous restart (Bits [7:6] = 01,
Bits [5:3] = 000 means no restart, Bits [5:3] =
111 means continuous restart)
3. Immediate shut down followed by no restart or
continuous restart (Bits [7:6] = 10, Bits [5:3] =
000 means no restart, Bits [5:3] = 111 means
continuous restart).
PMBus Adjustable Overcurrent Warning
The module can provide an overcurrent warning via the
PMBus. The threshold for the overcurrent warning can
be set using the parameter IOUT_OC_WARN_LIMIT.
This command uses the Linear data format with a two
byte data word where the upper five bits [7:3] of the high
byte represent the exponent and the remaining three
bits of the high byte [2:0] and the eight bits in the low
byte represent the mantissa. The exponent is fixed at
1 (decimal). The upper six bits of the mantissa are fixed

present and the output is enabled when the

set at 1.08V. The values associated with these
commands can be stored in non-volatile memory using
the STORE_DEFAULT_ALL command.
Note that separate response choices are possible for
output over voltage or under voltage faults.
The PGOOD terminal can be connected through a
pullup resistor (suggested value 100KΩ) to a source of
5VDC or lower.
PMBus Adjustable Input Undervoltage Lockout
The module allows adjustment of the input under voltage
lockout and hysteresis. The command VIN_ON allows
setting the input voltage turn on threshold, while the
VIN_OFF command sets the input voltage turn off
threshold. For the VIN_ON command, possible values
are 2.75V, and 3V to 14V in 0.5V steps. For the
VIN_OFF command, possible values are 2.5V to 14V in
0.5V steps. If other values are entered for either
command, they will be mapped to the closest of the
allowed values.
Measurement of Output Current, Output
Voltage and Input Voltage
The module is capable of measuring key module
parameters such as output current and voltage and input
voltage and providing this information through the
PMBus interface. Roughly every 200ȝs, the module
makes 16 measurements each of output current, voltage
and input voltage. Average values of of these 16
measurements are then calculated and placed in the
appropriate registers. The values in the registers can
then be read using the PMBus interface.
Both the VIN_ON and VIN_OFF commands use the
Linear format with two data bytes. The upper five bits
represent the exponent (fixed at -2) and the remaining
11 bits represent the mantissa. For the mantissa, the
four most significant bits are fixed at 0.
Measuring Output Current Using the PMBus
The module measures current by using the inductor
winding resistance as a current sense element. The
inductor winding resistance is then the current gain
factor used to scale the measured voltage into a current
reading. This gain factor is the argument of the
IOUT_CAL_GAIN command, and consists of two bytes
in the linear data format. The exponent uses the upper
five bits [7:3] of the high data byte in two-s complement
format and is fixed at 15 (decimal). The remaining 11
bits in twos complement binary format represent the
mantissa. During manufacture, each module is
calibrated by measuring and storing the current gain
factor into non-volatile storage.
Power Good
The module provides a Power Good (PGOOD) signal
that is implemented with an open-drain output to indicate
that the output voltage is within the regulation limits of
the power module. The PGOOD signal will be de-
asserted to a low state if any condition such as
overtemperature, overcurrent or loss of regulation
occurs that would result in the output voltage going
outside the specified thresholds. The PGOOD
thresholds are user selectable via the PMBus (the
default values are as shown in the Feature
Specifications Section). Each threshold is set up
symmetrically above and below the nominal value. The
POWER_GOOD_ON command sets the output voltage
level above which PGOOD is asserted (lower threshold).
For example, with a 1.2V nominal output voltage, the
POWER_GOOD_ON threshold can set the lower
threshold to 1.14 or 1.1V. Doing this will automatically
set the upper thresholds to 1.26 or 1.3V.
The current measurement accuracy is also improved by
each module being calibrated during manufacture with
the offset in the current reading. The
IOUT_CAL_OFFSET command is used to store and
read the current offset. The argument for this command
consists of two bytes composed of a 5-bit exponent
(fixed at -4d) and a 11-bit mantissa. This command has
a resolution of 62.5mA and a range of -4000mA to
+3937.5mA.
The POWER_GOOD_OFF command sets the level
below which the PGOOD command is de-asserted. This
command also sets two thresholds symmetrically placed
around the nominal output voltage. Normally, the
POWER_GOOD_ON threshold is set higher than the
POWER_GOOD_OFF threshold.
The READ_IOUT command provides module average
output current information. This command only supports
positive or current sourced from the module. If the
converter is sinking current a reading of 0 is provided.
The READ_IOUT command returns two bytes of data in
the linear data format. The exponent uses the upper five
bits [7:3] of the high data byte in two-s complement
format and is fixed at 4 (decimal). The remaining 11
bits in twos complement binary format represent the
mantissa with the 11th bit fixed at 0 since only positive
numbers are considered valid.
Both POWER_GOOD_ON and POWER_GOOD_OFF
commands use the Linear format with the exponent
fixed at 10 (decimal). The two thresholds are given by
VOUT (PGOOD _ ON ) = (POWER _ GOOD _ ON) × 2−10
VOUT (PGOOD _ OFF ) = (POWER _ GOOD _ OFF) × 2−10
Both commands use two data bytes with bit [7] of the
high byte fixed at 0, while the remaining bits are r/w and
used to set the mantissa using twos complement
representation. Both commands also use the
VOUT_SCALE_LOOP parameter so it must be set
correctly. The default value of POWER_GOOD_ON is
set at 1.1035V and that of the POWER_GOOD_OFF is

not corrected for temperature. The temperature

Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should
always be provided to help ensure reliable operation.
operation the temperatures at these points should not
exceed TBD. The output power of the module should
not exceed the rated power of the module (Vo,set x
Io,max).
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel. The test set-up
is shown in Figure 49. The preferred airflow direction
for the module is in Figure 50.

Surface Mount Information
Pick and Place
MSL Rating
The 6A Digital Pico DLynxTM modules use an open
frame construction and are designed for a fully
automated assembly process. The modules are fitted
with a label designed to provide a large surface area
for pick and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
temperatures of up to 300oC. The label also carries
product information such as product code, serial
number and the location of manufacture.
The 6A Digital Pico DLynxTM modules have a MSL
rating of 2.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. B (Handling,
Packing, Shipping and Use of Moisture/Reflow
Sensitive Surface Mount Devices). Moisture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages should
not be broken until time of use. Once the original
package is broken, the floor life of the product at
conditions of ≤ 30°C and 60% relative humidity varies
according to the MSL rating (see J-STD-033A). The
shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90%
relative humidity.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended inside nozzle diameter
for reliable operation is 3mm. The maximum nozzle
outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.
Bottom Side / First Side Assembly
This module is not recommended for assembly on the
bottom side of a customer board. If such an assembly
is attempted, components may fall off the module
during the second reflow process.
Lead Free Soldering
The 12VDigital Pico DLynxTM 6A modules are lead-free
(Pb-free) and RoHS compliant and are both forward
and backward compatible in a Pb-free and a SnPb
soldering process. Failure to observe the instructions
below may result in the failure of or cause damage to
the modules and can adversely affect long-term
reliability.
Figure 51. Recommended linear reflow profile
using Sn/Ag/Cu solder.
Post Solder Cleaning and Drying
Considerations
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a recommended
forced-air-convection reflow profile based on the
volume and thickness of the package (table 5-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using Sn/Ag/Cu
solder is shown in Fig. 51. Soldering outside of the
recommended profile requires testing to verify results
and performance.
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power module and the testability
of the finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures,
refer to Board Mounted Power Modules: Soldering and
Cleaning Application Note (AN04-001).
It is recommended that the pad layout include a test
pad where the output pin is in the ground plane.
The thermocouple should be attached to this test
pad since this will be the coolest solder joints. The
temperature of this point should be:
Maximum peak temperature is 260 C.
Minimum temperature is 235 C.
