Description
The Naos Raptor 60A SIP power modules are non-isolated dc-dc converters in an industry standard package that
can deliver up to 60A of output current with a full load efficiency of 92.1% at 3.3Vdc output voltage (VIN = 12Vdc).
These modules operate over a wide range of input voltage (VIN = 5Vdc-13.8Vdc) and provide a precisely regulated
output voltage from 0.6dc to 5.0Vdc, programmable via an external resistor. Features include remote On/Off,
adjustable output voltage, over current, over temperature 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.

Test Configurations
Design Considerations
CURRENT PROBE
The Naos Raptor 60A 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 polymer
and ceramic capacitors are recommended at the input
of the module. Figure 40 shows the input ripple
voltage for various output voltages at 60A of load
current with 2x22 µF or 4x22 µF ceramic capacitors
and an input of 12V.

The Naos Raptor 60A 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. 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

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. 60950-103, 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.

The Naos Raptor 60A power modules feature a
remote On/Off pin with positive logic. If not using the
On/Off pin, 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 typical average
output current during hiccup is 10% of Io,max.
Over Temperature Protection
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 135ºC
is exceeded at the thermal reference point Tred. 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, module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.

Output Voltage Programming
Monotonic Start-up and Shutdown
The output voltage of the Naos Raptor 60A module
can be programmed to any voltage from 0.6Vdc to
5.0Vdc by connecting a resistor between the Trim +
and Trim - pins of the module. Without an external
resistor between Trim + and Trim - pins, the output of
the module will be 0.6Vdc. To calculate the value of
the trim resistor, Rtrim for a desired output voltage,
use the following equation:
The Naos Raptor 60A modules have monotonic startup and shutdown behavior for any combination of
rated input voltage, output current and operating
temperature range.
Rtrim =
1.2
kΩ
(Vo − 0.6)
Rtrim is the external resistor in kΩ
Vo is the desired output voltage
Table 2 provides Rtrim values required for some
common output voltages.
By using a ±0.1% tolerance trim resistor with a TC of
±25ppm, a set point tolerance of ±0.8% can be
achieved as specified in the electrical specification.
The POL Programming Tool available at
www.lineagepower.com under the Design Tools
section, helps determine the required trim resistor
needed for a specific output voltage.

Feature Descriptions (continued)
Tunable LoopTM
The Naos Raptor 60A modules have a new feature
that optimizes transient response of the module called
TM
Tunable Loop . 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 SENSE and TRIM pins of the module, as
shown in Fig. 43. 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 30A to 60A 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
1880 µF, 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
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 setup is shown in Figure 44. The derating data applies
to airflow in either direction of the module’s axis.
The thermal reference points, Tref1 and Tref2 used in
the specifications are shown in Figure 45. For reliable
operation this temperatures 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 BoardMounted Power Modules” for a detailed discussion of
thermal aspects including maximum device
temperatures.

Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves
showing the maximum output current that can be
delivered at different local ambient temperatures (TA)
for airflow conditions ranging from natural convection
and up to 2m/s (400 ft./min) are shown in the
Characteristics Curves section.
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 the 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
representative for more details.
