High-Density Power Modules UCC2895 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 …
