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 modules operate over a wide range of input voltage (V 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 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.
