NCP1546 Overview
NCP1546 1.5 A, 170 kHz, Buck Regulator with Synchronization Capability The NCP1546 is a 1.5 A buck regulator IC operating at a fixed−frequency of 170 kHz. The device uses the V2t control architecture to provide unmatched transient response, the best overall regulation and the simplest loop pensation for today’s high−speed logic. The NCP1546 acmodates input voltages from 4.0 V to 40 V and contains synchronization...
