UCC28632 - High-Power Flyback Controller

This page provides the datasheet information for the UCC28632, a member of the UCC28630 High-Power Flyback Controller family.

Datasheet Summary

Description

The UCC2863x targets high-power, primary-side regulated flyback converters.

The ability to operate in both CCM and DCM make the device suitable for applications with a wide power range.

Features

  • 1 High-Power, Primary-Side CV/CC Regulation.
  • Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) Operation.
  • Built-In 700-V Start-Up Current Source.
  • Active X-Capacitor Discharge (UCC28630 and UCC28633).
  • Adjustable Constant-Current (CC) Mode Limiting (except for UCC28630).
  • High Gate Drive Current 1-A Source and 2-A Sink.
  • Low Power Modes for.
