Description

The Pico TLynxTM 6A 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

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

= 2.4Vdc-5.5Vdc) and provide a precisely regulated output voltage from 0.6Vdc to

IN

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.

Design Considerations

Input Filtering

The Pico TLynxTM 6A modules should be connected to a low ac­impedance 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.

To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 34 shows the
input ripple voltage for various output voltages at 6A of load
current with 1x22 µF or 2x22 µF ceramic capacitors and an input
of 5V. Figure 35 shows data for the 3.3Vin case, with 1x22µF or
2x22µF of ceramic capacitors at the input.

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.

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

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, 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.

The input to these units is to be provided with a fast-acting

Feature Descriptions

Remote On/Off

The Pico TLynxTM 6A 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 pull­up resistor and the module is OFF.

For negative logic On/Off modules, the circuit configuration is

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

Remote Sense

The Pico TLynxTM 6A 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.

Output Voltage Sequencing

The APTH006A0X modules include a sequencing feature, EZ­SEQUENCE 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
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.

For proper voltage sequencing, first, input voltage is applied to
the module. The On/Off pin of the module is left unconnected (or
tied to GND for negative logic modules or tied to V
logic modules) so that the module is ON by default. After
applying input voltage to the module, a minimum 10msec delay
is required before applying voltage on the SEQ pin. This delay
gives the module enough time to complete its internal power-up
soft-start cycle. During the delay time, the SEQ pin should be
held close to ground (nominally 50mV ± 20 mV). This is required
to keep the internal op-amp out of saturation thus preventing
output overshoot during the start of the sequencing ramp. By
selecting resistor R1 (see fig. 43) according to the following
equation

the voltage at the sequencing pin will be 50mV when the
sequencing signal is at zero.

Loop

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

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

Surface Mount Information

Pick and Place

The Pico TLynxTM 6A 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

o

C. The label also carries product information such as

300
product code, serial number and the location of manufacture.

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. If assembly on the bottom side is planned, please
contact Lineage Power for special manufacturing process
instructions.

Lead Free Soldering

The Pico TLynxTM 6A 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.

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 4-2). The suggested
Pb-free solder paste is Sn/Ag/Cu (SAC). A 6 mil thick stencil is
recommended. For questions regarding Land grid array(LGA)
soldering, solder volume; please contact Lineage Power for
special manufacturing process instructions.

TM

6A: Non-Isolated DC-DC Power Modules

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-STD­033A). 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.

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
