UCC24612 - High Frequency Synchronous Rectifier Controller

Description

UCC24612 is a high performance synchronous rectifier controller and driver for standard and logiclevel N-channel MOSFET power devices.

By implementing a near-ideal diode emulation UCC24612 reduces losses of the output rectifier and indirectly the primary side losses.

Features

  • 1 Supports Topologies such as Active Clamp Flyback, QR, DCM, CCM Flyback and LLC.
  • MOSFET VDS Sensing up to 230 V.
  • Operating Frequency Up to 1 MHz.
  • 1 MHz for UCC24612-1.
  • 800 kHz for UCC24612-2.
  • Wide VDD Range Allows for Direct Bias from 5-V to 28-V Output Systems.
  • 4-A Sink, 1-A Source Gate Driver with Proportional Gate Drive.
  • Adaptive Minimum Off-time for Increased Noise Immunity.
  • Cycle Limit Pre-Turn-off Improves Ef.
