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 (V
IN
= 12Vdc).
These modules operate over a wide range of input voltage (V
IN
= 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,
TM
adjustable output voltage, over current and over voltage protection. A new feature, the Tunable Loop , 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.

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.
