From Texas Instruments, a range of Pulse Width Modulation controllers and associated devices to suit a variety of applications and specifications.

The Texas Instruments UCC3895 is a phase-shift 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. The device allows constant frequency pulse-width modulation in conjunction with resonant zero-voltage switching to provide high efficiency at high frequencies. The part is used either as a voltage-mode or current-mode controller.
