FGSR12SR6003*A
3-14.4Vdc Input, 3A, 0.6-5.5Vdc Output
The Tomodachi Series of non-isolated dc-dc
converters deliver exceptional electrical and thermal
performance in DOSA based footprints for
Point-of-Load converters. Operating from
a
3.0Vdc-14.4Vdc input, these are the converters of
choice for Intermediate Bus Architecture (IBA) and
Distributed Power Architecture applications that
require high efficiency, tight regulation, and high
reliability in elevated temperature environments with
low airflow. The Tunable Loop™ 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.
The FGSR12SR6003*A converter of the Tomodachi
Series delivers 3A of output current at a tightly
regulated programmable output voltage of 0.6Vdc to
5.5Vdc. The thermal performance of the
FGSR12SR6003*A is best-in-class: No derating is
needed up to 85℃, under natural convection.

maximum output capacitance as specified in the
electrical specification table. Optimal performance of
the module can be achieved by using the Tunable
Loop™ feature described later in this data sheet.
Design Considerations
Input Filtering
The FGSR12SR6003*A converter 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 Consideration
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

12V.
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
The FGSR12SR6003*A is designed for low output
ripple voltage and will meet the maximum output
ripple specification with 0.1uF ceramic and 10uF
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 fast
-acting fuse with a maximum rating of 5A, 125Vdc 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. Fig-2
provides output ripple information for different
external capacitance values at various Vo and a full

The FGSR12SR6003*A power modules feature an
On/Off pin for remote On/Off operation. Two On/Off
logic options are available. In the Positive Logic
On/Off option, (device code suffix “P” - see Ordering
Information), the module turns ON during a logic High
on the On/Off pin and turns OFF during a logic Low.
With the Negative Logic On/Off option, (device code
suffix “N” - see Ordering Information), the module
turns OFF during 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.

For positive logic modules, the circuit configuration
for using the On/Off pin is shown in Fig-3. When the
external transistor Q1 is in the OFF state, the internal
PWM Enable signal is pulled high through an internal
resistor and the external pullup resistor and the

RTRIM
[kΩ]
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-5. 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.
(VO-REQ - 0.6)
Rtrim is the external resistor in kohm
Vo-req is the desired output voltage
Note that the tolerance of a trim resistor will affect the
tolerance of the output voltage. Standard 1% or 0.5%
resistors may suffice for most applications; however,
a tighter tolerance can be obtained by using two
resistors in series instead of one standard value
resistor.
Table 1 lists calculated values of RTRIM for common
output voltages. For each value of RTRIM, Table 1 also
shows the closest available standard resistor value.

Dual Layout
Identical dimensions and pin layout of Analog and
Digital 3A Tomodachi modules permit migration from

layout. To support this, 2 separate Trim Resistor
locations have to be provided in the layout. For the
digital modules, the resistor is connected between

Over-Current 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.

Caution – Do not connect SIG_GND to GND elsewhere in
the layout
Fig-9: Layout to support either Analog or Digital
6A Tomodachi modules on the same pad.
Over-Temperature Protection
Tunable Loop™
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit
will shutdown if the overtemperature threshold of
135oC(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.
The module has a feature that optimizes transient
response of the module called Tunable Loop™
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple
and noise (see Fig-10) 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.
Input Under-Voltage Lockout (UVLO)
At input voltages below the input under-voltage
lockout limit, the module operation is disabled. The
module will begin to operate at an input voltage
above the under-voltage lockout turn-on threshold.
The Tunable Loop™ allows the user to externally
adjust the voltage control loop to match the filter
network connected to the output of the module. The
Tunable Loop™ is implemented by connecting a
series R-C between the VS+ and TRIM pins of the
module, as shown in Fig-10. This R-C allows the user
to externally adjust the voltage loop feedback
compensation of the module.
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 over-temperature, over-current or

R
TUNE and CTUNE for different values of ceramic output
capacitors up to 1000uF that might be needed for an
application to meet output ripple and noise
requirements. Selecting RTUNE and CTUNE according to
Table 2 will ensure stable operation of the module. In
applications with tight output voltage limits in the
presence of dynamic current loading, additional
output capacitance will be required. Table 3 lists
recommended values of RTUNE and CTUNE in order to
meet 2% output voltage deviation limits for some
common output voltages in the presence of a 3A to
3A step change (50% of full load), with an input
voltage of 12V.

function of ambient temperature and airflow), ripple
and noise, transient response to load step changes,
start-up and shutdown characteristics.
Figures showing data plots and waveforms for
different output voltages are presented in the
following pages.
Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should
always be provided to help ensure reliable operation.
Fig-12: Preferred airflow direction and location
of hot-spot of the module (Tref).
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 Fig-11. The preferred airflow
direction for the module is in Fig-12.
The main heat dissipation method of this converter is
to transfer its heat to the system board. Thus, if the
temperature of the system board goes high, even
with the low ambient temperature, it may exceed the
guaranteed temperature of components.

Surface Mount Information
Pick and Place
instructions. The recommended linear reflow profile
using Sn/Ag/Cu solder is shown in Fig-49. Soldering
outside of the recommended profile requires testing
to verify results and performance.
The 3A Analog Tomodachi 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 300°C. The label also carries
product information such as product code, serial
number and the location of manufacture.
MSL Rating
The 3A Analog Tomodachi modules have a MSL
rating of 2a.
Storage and Handling
The recommended storage environment and
handling procedures for moisture-sensitive surface
mount packages is detailed in J-STD-033 Rev. A
(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 7mm.
Bottom Side / First Side Assembly
300
Per J-STD-020 Rev. C
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 modules are lead-free (Pb-free) and RoHS
compliant and fully compatible in a Pb-free 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.
Reflow Time (Seconds)

Post Solder Cleaning and Drying
Considerations
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 4-2).
The suggested Pb-free solder paste is Sn/Ag/Cu
(SAC). For questions regarding Land grid array
(LGA) soldering, solder volume; please contact
Lineage Power for special manufacturing process
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).
