Description

The Pico TLynx^TM6A power modules are non-isolated dc-dc converters that can deliver up to 6A of output current.

These modules operate over a wide range of input voltage (V_IN= 2.4Vdc-5.5Vdc) and provide a precisely regulated

output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off,

adjustable output voltage, over current and overtemperature protection, and output voltage sequencing (APTH

versions). A new feature, the Tunable Loop^TM, 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.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to an

integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included;

however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies

require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information

provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating

can be used. Refer to the fuse manufacturer’s data sheet for further information.

Output Filtering

20

The Pico TLynx^TM6A modules are designed for low

output ripple voltage and will meet the maximum output

ripple specification with 0.11 µF ceramic and 10 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

15

1x10uF External Cap

and noise of the module.

Second, the dynamic

response characteristics may need to be customized to

a particular load step change.

0

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 36 provides

output ripple information for different external

capacitance values at various Vo and for load currents

of 6A while maintaining an input voltage of 5V. Fig 37

shows the performance with a 3.3V input. 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 achieved by using the Tunable

Loop^TMfeature described later in this data sheet.

installed in compliance with the spacing and separation

requirements of the end-use safety agency standards,

i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE

0850:2001-12 (EN60950-1) Licensed.

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.

MODULE

Remote On/Off

The Pico TLynx^TM6A 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 “4” 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, (no device code suffix see Ordering Information),

the module turns OFF during logic High and ON during

logic Low. The On/Off signal is 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 Figure 38. When the

external transistor Q1 is in the OFF state, Q2 is ON, the

internal PWM Enable signal is pulled low and the

module is ON. When transistor Q1 is turned ON, the

On/Off pin is pulled low, Q2 is turned off and the internal

PWM Enable signal is pulled high through the 100K

internal pull-up resistor and the module is OFF.

On/Off logic.

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.

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 140^oC is

exceeded at the thermal reference point T_ref. The

thermal shutdown is not intended as a guarantee that

the unit will survive temperatures beyond its rating.

Once the unit goes into thermal shutdown it will then

wait to cool before attempting to restart.

Output Voltage Programming

For negative logic On/Off modules, the circuit

The output voltage of the Pico TLynx^TM6A module can

be programmed to any voltage from 0.6Vdc to 3.63Vdc

by connecting a resistor between the Trim and 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. 40. The Upper Limit

curve shows that the entire output voltage range is

available with the maximum input voltage of 5.5V. The

Lower Limit curve shows that for output voltages of 1.8V

and higher, the input voltage needs to be larger than the

minimum of 2.4V.

configuration is shown in Fig. 39. The On/Off pin should

be pulled high with an external pull-up resistor

(suggested value for the 2.4V to 5.5Vin range is

3.6Kohms). When transistor Q1 is in the OFF state, the

On/Off pin is pulled high and the module is OFF. The

On/Off threshold for logic High on the On/Off pin

depends on the input voltage and its minimum value is

V_IN– 1.6V. To turn the module ON, Q1 is turned ON

pulling the On/Off pin low.

Remote Sense

The Pico TLynx^TM6A modules have a Remote Sense

feature to minimize the effects of distribution losses by

regulating the voltage at the SENSE pin. The voltage

between the SENSE pin and VOUT pin must not

exceed 0.5V. Note that the output voltage of the module

cannot exceed the specified maximum value. This

includes the voltage drop between the SENSE and Vout

pins. When the Remote Sense feature is not being

used, connect the SENSE pin to the VOUT pin.

Without an external resistor between Trim and GND

pins, the output of the module will be 0.6Vdc. To

calculate the value of the trim resistor, Rtrim for a

desired output voltage, use the following equation:

Figure 43. Circuit showing connection of the

sequencing signal to the SEQ pin.

Output Voltage Sequencing

After the 10msec delay, an analog voltage is applied to

the SEQ pin and the output voltage of the module will

track this voltage on a one-to-one volt bases until the

output reaches the set-point voltage. 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.

The APTH006A0X modules include 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, either tie the SEQ pin to V^INor

leave it unconnected.

When an analog 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

SEQ voltage must be set higher than the set-point

voltage of the module. The output voltage follows the

voltage on the SEQ pin on a one-to-one volt basis. By

connecting the SEQ pins of multiple modules together,

all modules can track their output voltages to the

voltage applied on the SEQ pin.

When using the EZ-SEQUENCE^TMfeature to control

start-up of the module, pre-bias immunity during start-up

is disabled. The pre-bias immunity feature of the

module relies on the module being in the diode-mode

during start-up. When using the EZ-SEQUENCE^TM

feature, modules goes through an internal set-up time of

10msec, and will be in synchronous rectification mode

when the voltage at the SEQ pin is applied. This will

result in the module sinking current if a pre-bias voltage

is present at the output of the module. When pre-bias

immunity during start-up is required, the EZ-

.

External capacitors are usually added to the output of

the module for two reasons: to reduce output ripple and

noise (see Figures 36 and 37) 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.

Thermal Considerations

Power modules operate in a variety of thermal

environments; however, sufficient cooling should always

be provided to help ensure reliable operation.

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 45. The preferred airflow direction

Post Solder Cleaning and Drying

Considerations

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
