UCC3895 - BiCMOS Advanced Phase Shift PWM Controller

This page provides the datasheet information for the UCC3895, a member of the UCC1895 BiCMOS Advanced Phase Shift PWM Controller family.

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.

Features

  • Programmable Output Turn-on Delay.
  • Adaptive Delay Set.
  • Bidirectional Oscillator Synchronization.
  • Capability for Voltage Mode or Current Mode Control.
  • Programmable Soft Start/Soft Stop and Chip Disable via a Single Pin.
  • 0% to 100% Duty Cycle Control.
  • 7MHz Error Amplifier.
  • Operation to 1MHz.
  • Low Active Current Consumption (5mA Typical @ 500kHz).
  • Very Low Current Consumption During Undervoltage Lock-out (150µ.
