Overview: Product Folder Order Now Technical Documents Tools & Software Support & munity UCC1895, UCC2895, UCC3895 SLUS157Q – DECEMBER 1999 – REVISED OCTOBER 2019 UCCx895 BiCMOS Advanced 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.

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.

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.
