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.
RoHS Compliant

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.

voltages with 1x22 µF or 2x22 µF ceramic
capacitors at the input (6A load). 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

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.
Feature Descriptions (continued)
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 Set
Point Area plot in Fig. 49. The Upper Limit curve shows
that for output voltages of 0.9V and lower, the input
voltage must be lower than the maximum of 14V. The
Lower Limit curve shows that for output voltages of 3.8V
and higher, the input voltage needs to be larger than the
minimum of 4.5V.

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.lineagepower.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

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 Lineage Power 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 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 technical
representative for more details.
