NCP1581
NCP1581 is High Frequency Synchronous Step-Down PWM Controller manufactured by onsemi.
High Frequency Synchronous Step Down PWM Controller for Tracking Applications
The NCP1581 controller IC is designed to provide a simple synchronous buck regulator for on- board DC to DC applications in a 14- pin SOIC. The NCP1581 is designed specifically for tracking applications by providing the track input.
The NCP1581 operates at a fixed internal 400 k Hz switching frequency allowing the use of small external ponents. The device Features 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 detected.
