Description
The Boost power modules are non-isolated dc-dc converters that can deliver up to 65W of output power. The module can
operate over a wide range of input voltage (VIN = 8Vdc-16Vdc) and provide an adjustable 16 to 34VDC output. The output
voltage is programmable via an external resistor. Features include remote On/Off, over current and over temperature
protection. The module also includes the Tunable LoopTM feature that 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
To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 25 shows
the input ripple voltage
300
Output Ripple (mVp-p)
The ABXS002Open Frame 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.

Output Filtering
These modules are designed for low output ripple voltage and
will meet the maximum output ripple specification with 66uF
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.
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
ANSI/UL 62368-1 and CAN/CSA C22.2 No. 62368-1
Recognized,
DIN
VDE0868-1/A11:2017
(EN623681:2014/A11:2017).
For the converter output to be considered meeting the
Requirements of safety extra-low voltage (SELV) or ES1, the
input must meet SELV/ES1 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 12A fuse 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 26 provides output ripple information,
measured with a scope with its Bandwidth limited to 20MHz
for different external capacitance values at various Vo. 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 LoopTM feature
described later in this data sheet.

Figure28. Circuit configuration for programming output
voltage using an external resistor.
Analog Feature Descriptions
Remote On/Off
The ABXS002 Open Frame power modules feature an On/Off
pin for remote On/Off operation.
For negative logic On/Off modules, the circuit configuration is
shown in Fig. 27. The On/Off pin should be pulled high with an
external pull-up resistor. When Q1 turns On, the On/OFF pin is
pulled low. This turns Q2 off and the internal PWM Enable is
pulled high and the module turns on. When Q1 is Off, Q2 turns
ON and the internal PWM Enable is pulled low and the module
turns OFF
Without an external resistor between TRIM and sGND pins,
each output of the module will be the same as input voltage.
The value of the trim resistor, Rtrim for a desired output
voltage, should be as per the following equation:
1.2
Rtrim =
x 200.5k
(Vo − 1.2 )
Rtrim is the external resistor in kΩ
Vo is the desired output voltage.
Table 1 provides Rtrim values required for some common
output voltages.

Monotonic Start-up and Shutdown
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
Analog Voltage Margining
The module can start into a prebiased output as long as the
prebias voltage is 0.5V less than the set output voltage.
Analog Output Voltage Programming
The output voltage of each output of the module can be
programmable to any voltage from 16VDC to 34VDC by
connecting a resistor between the Trims and GND pins of the
module.
V IN(+)
V O(+)
ON/OFF
TRIM
Vout
Output voltage margining can be implemented in the module
by connecting a resistor, Rmargin-up, from the Trim pin to the
ground pin for margining-up the output voltage and by
connecting a resistor, Rmargin-down, from the Trim pin to output
pin for margining-down. Figure 30 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at www.gecriticalpower.com
under the Downloads section, also calculates the values of
Rmargin-up and Rmargin-down for a specific output voltage and %
margin. Please consult your local GE Critical Power technical
representative for additional details.

MODULE
The module has a feature that optimizes transient response of

Q2
Trim
External capacitors are usually added to the output of the
module for two reasons: to reduce output ripple and noise
(see Figure 26) 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 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 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 VOUT and TRIM pins
of the module, as shown in Fig. 31. This R-C allows the user to
externally adjust the voltage loop feedback compensation of
the module.

Overtemperature Protection
RTUNE
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 129oC(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.

Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.

Recommended values of RTUNE and CTUNE for different output
capacitor combinations are given in Table 2. Table 2 shows the
recommended values of RTUNE and CTUNE for different values of
ceramic output capacitors up to 30x01uF 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

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 terminal can be
connected through a pullup resistor (suggested value 10kΩ) to
a source of 5VDC or lower.

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 32. The preferred
airflow direction for the module is in Figure 33.
The thermal reference points, Tref used in the specifications
are also shown in Figure 33. For reliable operation the
temperatures at the Q1 should not exceed 120oC. The output
power of the module should not exceed the rated power of
the module (Vo,set x Io,max).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-Mounted
Power Modules” for a detailed discussion of thermal aspects
including maximum device temperatures.

Pick and Place
The ABXS002 Open Frame 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.
Stencil and Nozzle Recommendations
Stencil thickness of 6 mils minimum must be used for this
product. 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.
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 JSTD-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.

Post Solder Cleaning and Drying Considerations
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 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 longterm reliability.
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).
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. D
(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). The
recommended linear reflow profile using Sn/Ag/Cu solder is
shown in Fig. 35. Soldering outside of the recommended profile
requires testing to verify results and performance.
MSL Rating
The ABXS002 Open Frame 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).
