Description
The NQR010A0X4 SIP power modules are non-isolated dc-dc converters in an industry standard package that can
deliver up to 10A of output current with a full load efficiency of 94% at 5Vdc 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, adjustable
output voltage, over current and over temperature 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.
