Description

The Naos Raptor 50 SIP power modules are non-isolated dc-dc converters in an industry standard package that can
deliver up to 50A of output current with a full load efficiency of 87% at 1.8Vdc output voltage (V
modules operate over a wide range of input voltage (V
voltage from 0.6dc to 2.0Vdc, programmable via an external resistor. Features include remote On/Off, 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 fast­acting fuse with a maximum rating of 30A (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.
