DESCRIPTION
The NX4125 is an integrated 2A monolithic step-down n switching regulator with feedforward voltage mode con- n trol. It operates from an input voltage 2.5V to 5.5V which n is ideal for the application with single cell Li-Ion battery n as well as other 3.3V, 5V input bus supply applications. Switching frequency is fixed around 800kHz, small sur- n face mount inductors and capacitors are allowed to use. n Other Features includes: Over current protection, Over n voltage protection, Over temperature protection, <1uA n shut-down current and power good indicator available. n
