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 (V
IN
= 12Vdc).
These modules operate over a wide range of input voltage (V
IN
= 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
Loop
TM
, allows the user to optimize the dynamic response of the converter to match the load.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.
