To maintain low-noise and ripple at the input voltage, it is
critical to use low ESR capacitors at the input to the module.

models using a 150 µF low ESR polymer capacitor (Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel

much lower input voltage ripple when input capacitance is
increased to 450 µF (3 x 150 µF) polymer capacitors in parallel with 94 µF (2 x 47 µF) ceramic capacitor.

Austin LynxTM SIP Non-Isolated dc-dc Power Modules:
3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A
Design Considerations (continued)
Input Source Impedance (continued)
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can
affect the stability of the module. An input capacitance must
be placed close to the input pins of the module, to filter ripple
current and ensure module stability in the presence of inductive traces that supply the input voltage to the module.
Safety Considerations
For safety-agency approval of the system in which the power
module is used, the power module must be installed in compliance with the spacing and separation requirements of the
end-use safety agency standard, i.e., UL60950, CSA C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).
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 ELV (extra-low voltage) outputs when
all inputs are ELV.
The input to these units is to be provided with a maximum
20A time-delay fuse in the unearthed lead.

Feature Descriptions
Table 1. Austin Lynx™ Trim Values
Remote On/Off
The Austin Lynx™ SIP power modules feature an
On/Off pin for remote On/Off operation. If not using the
remote On/Off pin, leave the pin open (module will be On).
The On/Off pin signal (Von/off) is referenced to ground. To
switch the module on and off using remote On/Off, connect
an open collector pnp transistor between the On/Off pin and
the VI pin (see Figure 20).
During a logic-low when the transistor is in the Off state, the
power module is On and the maximum
Von/off generated by the module is 0.3V. The maximum
leakage current of the switch when Von/off = 0.3V and VI =
5.5V (Vswitch = 5.2V) is 10 µA. During a logic-high when the
transistor is in the active state, the power module is Off. During this state, Von/off = 2.5V to 5.5V and the maximum Ion/
off = 1mA.

Output Voltage Set-Point Adjustment
(Trim)
Output voltage set-point adjustment allows the output voltage set point to be increased or decreased by connecting
either an external resistor or a voltage source between the
TRIM pin and either the VO pin (decrease output voltage) or
GND pin (increase output voltage).
For TRIM-UP using an external resistor, connect Rtrim-up
between the TRIM and GND pins (Figure 21). The value of
Rtrim-up defined as:

|DVout| is the desired output voltage set-point adjustment
Rbuffer (internal to the module) is defined in Table 1 for various models.

For trim-down using an external resistor, connect Rtrimdown between the TRIM and VOUT pins of the module
(Figure 22). The value of Rtrim-down is defined as:

For example, to trim-down the output voltage of 2.5 V module (AXH010G) by 8% to 2.3V, Rtrim-down is
calculated as follows:
ΔV out = 0.2V
V out = 2.5V

regulating the voltage at the load via the SENSE and GND
connections (See 23). The voltage between the SENSE pin
and VO pin must not exceed 0.5V. Although both the Remote
Sense and Trim features can each increase the output voltage (VO), the maximum increase is not the sum of both. The
maximum VO increase is the larger of either the Remote
Sense or the Trim.
The amount of power delivered by the module is defined as
the output voltage multiplied by the output current (VO x IO).
When using SENSE and/or TRIM, the output voltage of the
module can increase which, if the same output current is
maintained, increases the power output by the module. Make
sure that the maximum output power of the module remains
at or below the maximum rated power. When pin 3 is present
but the Remote Sense feature is not being used, leave Sense
pin disconnected.

Overcurrent Protection
For Trim-up using an external voltage source, apply a voltage
from TRIM pin to ground using the following equation:
R buffer
V trim-up = 0.8 – ΔV out x -----------------30100
To provide protection in a fault condition, the unit is equipped
with internal overcurrent protection. The unit operates normally once the fault condition is removed.
For Trim-down using an external voltage source, apply a voltage from TRIM pin to ground using the following equation:
R buffer
V trim-down = 0.8 + ΔV out x -----------------30100
Vtrim-up is the external source voltage for trim-up
Vtrim-down is the external source voltage for trim-down
|DVout| is the desired output voltage set-point adjustment
Rbuffer (internal to the module) is defined in Table 3 for various models
If the TRIM feature is not being used, leave the TRIM pin disconnected.
The power module will supply up to 170% of rated current for
less than 1.25 seconds before it enters thermal shutdown.
Overtemperature Protection
To provide additional protection in a fault condition, the unit is
equipped with a nonlatched thermal shutdown circuit. The
shutdown circuit engages when Q1 or Q2 (shown in Figure
24) exceeds approximately 110 °C. The unit attempts to
restart when Q1 or Q2 cool down and cycles on and off while
the fault condition exists. Recovery from shutdown is accomplished when the cause of the overtemperature condition is
removed.
Remote Sense
Austin Lynx™ SIP power modules offer an option for a
Remote Sense function. When the Device Code description
includes a suffix “3”, pin 3 is added to the module and the
Remote Sense is an active feature. See the Ordering Information at the end of this document for more information.
Remote Sense minimizes the effects of distribution losses by

Thermal Considerations
Convection Requirements for cooling
The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to
help ensure reliable operation of the unit. Heat is removed
by conduction, convection, and radiation to the surrounding
environment.
The thermal data presented is based on measurements
taken in a wind tunnel. The test setup shown in Figure 25
was used to collect data for Figures 26
and 27. Note that the airflow is parallel to the long axis of the
module as shown in Figure 24 and derating applies accordingly.
To predict the approximate cooling needed for the module,
refer to the Power Derating curves in Figures 26 and 27.
These derating curves are approximations of the ambient
temperatures and airflows required to keep the power module temperature below its maximum rating. Once the module
is assembled in the actual system, the module’s temperature
should be checked as shown in Figure 24 to ensure it does
not exceed 110 °C.
Proper cooling can be verified by measuring the power module’s temperature at Q1-pin 6 and Q2-pin 6 as shown in Figure 24.

Through-Hole Lead-Free Soldering Information
The RoHS-compliant through-hole products use the SAC
(Sn/Ag/Cu) Pb-free solder and RoHS-compliant components.
They are designed to be processed through single or dual
wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of 3°C/s is
suggested. The wave preheat process should be such that
the temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot temperature is
260°C, while the Pb-free solder pot is 270°C max. Not all
RoHS-compliant through-hole products can be processed
with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage
Power representative for more details.
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 Lineage
Power Board Mounted Power Modules: Soldering and
Cleaning Application Note (AP01-056EPS).
Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These requirements state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module
is C00 (per J specification).
