The 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 a.
•1 Programmable-output turnon delay
• Adaptive delay set
• Bidirectional oscillator synchronization
• Voltage-mode, peak current-mode, or average
current-mode control
• Programmable soft start, soft stop, and chip
disable via a single pin
• 0% to 100% duty-cycle control
• 7-MHz error amplifier
