Description
The NQR002A0X4 SIP power modules are non-isolated dc-dc converters in an industry standard package that can
deliver up to 2A of output current with a full load efficiency of TBD at 3.3Vdc output voltage (V
modules operate over a wide range of input voltage (V
= 3Vdc-14Vdc) and provide a precisely regulated output
IN
voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable
output voltage, over current and over temperature protection. A new feature, the Tunable Loop
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.
