UCC2897A Datasheet (Texas Instruments) - Active Clamp PWM Controller

UCC2897A, Active Clamp PWM Controller

The UCC2897A PWM controller simplifies implementation of the various active clamp or reset and synchronous rectifier switching power topologies.

The UCC2897A is a peak current-mode fixedfrequency high-performance pulse-width modulator.

The controller includes the logic and the drive capability for
