UCC2897 Overview
The UCC2897 PWM controller simplifies implementation of the various active clamp/reset and synchronous rectifier switching power topologies. Based on the UCC2891 active-clamp controller the UCC2897 is a peak current-mode, fixedfrequency, high-performance pulse width modulator. It includes the logic and the drive capability for the P-channel auxiliary switch along with a simple method of programming the critical...
