NCP1581: Synchronous Buck Controller, High Frequency, PWM, for Tracking Applications

The NCP1581 Synchronous Buck Controller IC is designed to provide a simple synchronous buck regulator for on-board DC-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 kHz switching frequency allowing the use of small external components. 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.
