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 (VIN = 12Vdc). These
modules operate over a wide range of input voltage (VIN = 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 LoopTM, allows the user to
optimize the dynamic response of the converter to match the load.
