NCP1581 controller equivalent, high frequency synchronous step-down pwm controller.
a programmable soft start set by an external capacitor, under−voltage lockout and output under−voltage detection that latches off the device when an output short is detec.
The NCP1581 controller IC is designed to provide a simple synchronous buck regulator for on−board DC to DC applications .
