Description
The Naos Raptor 3A SIP power modules are non-isolated dc-dc converters in an industry standard package that can deliver up
to 3A of output current with a full load efficiency of 93% 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
voltage protection. A new feature, the Tunable LoopTM, allows the user to optimize the dynamic response of the converter to
match the load.

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 being part of a complex 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 5 A (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 Naos Raptor 3A 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.
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 3A of
load current with 1x10 µF or 1x22 µF ceramic capacitors and an input
of 12V.

Output Filtering
The Naos Raptor 3A 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 3A. 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 ANSI/UL* 62368-1 and
CAN/CSA+ C22.2 No. 62368-1 Recognized, DIN VDE 0868-
1/A11:2017 (EN62368-1:2014/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 fast-acting fuse with
a maximum rating of 5A in the positive input lead. 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 recommended protection device
value, and
2. the module is evaluated in the end-use equipment.
Feature Descriptions
Remote On/Off
The Naos Raptor 3A power 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 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.
Feature Descriptions (continued)
Output Voltage Programming
The output voltage of the Naos Raptor 3A 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

Without an external resistor between Trim+ and GND pins, the

trim resistor, Rtrim for a desired output voltage, use the following
equation:
Rtrim is the external resistor in kΩ
Vo is the desired output voltage

voltages.

By using a ±0.5% tolerance trim resistor with a TC of ±25ppm, a set

specification. The POL Programming Tool available at

voltage.

Voltage Margining
Output voltage margining can be implemented in the Naos Raptor 3A
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 3A 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 3A 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 1.5A to 3A 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.
