UCC2895-EP Overview
Description
The UCC2895-EP is a phase-shift pulse-width modulation (PWM) controller that implements control of a full-bridge power stage by phase shifting the switching of one half bridge with respect to the other. It allows constant frequency PWM in conjunction with resonant zero-voltage switching to provide high efficiency at high frequencies.
