UCC2895 - Phase-Shift PWM Controller

General Description

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.

Key Features

  • 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.
  • Operation to 1 MHz.
  • Typical 5-mA operating current at 500 kHz.
  • Very low 150-μA current during UVLO 2.
