Overview

NCP1581 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 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.
Features • Power up Sequencing / Tracking • Enable Input • Internal 400...
