DESCRIPTION
The UCC2895-Q1 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. The device can be used either as a voltage-mode or...
