Description
The Naos Raptor 6A SIP power modules are non-isolated dc-dc converters in an industry standard package that can
deliver up to 6A of output current with a full load efficiency of 91.5% at 3.3Vdc output voltage (VIN = 12Vdc). These
modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage
from 0.59Vdc to 6Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage,
over current and over temperature protection. A new feature, the Tunable LoopTM, allows the user to optimize the
dynamic response of the converter to match the load.

Design Considerations
Input Filtering
The Naos Raptor 6A module should be connected to a low-
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.
To minimize input voltage ripple, low-ESR ceramic or polymer
capacitors are recommended at the input of the module. Figure 46
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 12V.

Input voltage is 12V.
Output Filtering
The Naos Raptor 6A modules are designed for low output ripple
voltage and will meet the maximum output ripple specification
with no external capacitors. 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.
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 ceramic and polymer are recommended to improve
the dynamic response of the module. Figure 47 provides output
ripple information for different external capacitance values at
various Vo and for a load current of 6A. 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.

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.
An input fuse for the module is recommended. Due to the wide
input voltage and output voltage ranges of the module, different
fuse ratings are recommended as shown in Table 1. These are
suggested “maximum” fuse ratings. However, for optimum circuit
protection, the fuse value should not be any larger than required in
the end application. As an option to using a fuse, no fuse is
required, if the module is
1. powered by a power source with current limit protection
set point less than the protection device value listed in
Table 1, and
2. the module is evaluated in the end-use equipment.

Feature Descriptions
Remote On/Off
The Naos Raptor 6A modules feature an On/Off pin with positive
logic for remote On/Off operation. If the On/Off pin is not being
used, leave the pin open (the module will be ON, except for the -49
option modules where leaving the pin open will cause the module
to remain OFF). The On/Off signal (VOn/Off) is referenced to ground.
During a Logic High on the On/Off pin, the module remains ON.
During Logic-Low, the module is turned OFF.

Overcurrent 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. The average
output current during hiccup is 10% IO, max.
Overtemperature Protection
To provide protection in a fault condition, these modules are
equipped with a thermal shutdown circuit. The unit will shut down
if the overtemperature threshold of 130ºC is exceeded at the
thermal reference point Tref. 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.
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.

Output Voltage Programming
The output voltage of the Naos Raptor 6A module can be
programmed to any voltage from 0.59dc to 6Vdc 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 Margining
Output voltage margining can be implemented in the Naos Raptor
6A modules 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 51 shows the circuit configuration for
output voltage margining. The POL Programming Tool, available at
www.gecriticalpower.com under the Design Tools section, also
calculates the values of Rmargin-up and Rmargin-down for a specific
output voltage and % margin. Please consult your local GE
technical representative for additional details.

Monotonic Start-up and Shutdown
The Naos Raptor 6A modules have monotonic start-up and
shutdown behavior for any combination of rated input voltage,
output current and operating temperature range.
Tunable LoopTM
The Naos Raptor 6A modules have a new feature that optimizes
transient response of the module called Tunable LoopTM. External
capacitors are usually added to improve output voltage transient
response due to load current changes. Sensitive loads may also
require additional output capacitance to reduce output ripple and
noise. 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.
To use the additional external capacitors in an optimal manner, the
Tunable LoopTM feature allows the loop to be tuned externally by
connecting a series R-C between the VOUT and TRIM pins of the
module, as shown in Fig. 52. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the module to
match the filter network connected to the output of the module.
Recommended values of RTUNE and CTUNE are given in Tables 3 and
4. 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 6A step change (50% of full
load), with an input voltage of 12V. Table 4 shows the
recommended values of RTUNE and CTUNE for different values of
ceramic output capacitors up to 1000uF, again for an input voltage
of 12V. The value of RTUNE should never be lower than the values
shown in Tables 3 and 4. Please contact your GE technical
representative to obtain more details of this feature as well as for
guidelines on how to select the right value of external R-C to tune
the module for best transient performance and stable operation
for other output capacitance values.

Thermal Considerations
Power modules operate in a variety of thermal environments;
however, sufficient cooling should 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 53. The preferred airflow direction for the
module is in Figure 54.
Figure 53. Thermal Test Set-up.
The thermal reference point, Tref used in the specifications of
thermal derating curves is shown in Figure 54. For reliable
operation this temperature 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
Figure 54. Tref Temperature measurement location.
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 Modules: Soldering and
Cleaning Application Note.
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 3C/s is suggested. The wave preheat
process should be such that the temperature of the power module
board is kept below 210C. For Pb solder, the recommended pot
temperature is 260C, while the Pb-free solder pot is 270C 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 GE technical
representative for more details.
