Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity UCC28950 SLUSA16D – MARCH 2010 – REVISED NOVEMBER 2016 UCC28950 Green Phase-Shifted Full-Bridge Controller With Synchronous Rectification.

General Description

The UCC28950 enhanced phase-shifted controller builds upon Texas Instrument’s industry standard UCx895 phase-shifted controller family with enhancements that offer best in class efficiency in today’s high performance power systems.

The UCC28950 implements advanced control of the fullbridge along with active control of the synchronous rectifier output stage.

The primary-side signals allow programmable delays to ensure ZVS operation over wide-load current and input voltage range, while the load current naturally tunes the secondary-side synchronous rectifiers switching delays, maximizing overall system efficiency.

Key Features

  • 1 Enhanced Wide Range Resonant Zero Voltage Switching (ZVS) Capability.
  • Direct Synchronous Rectifier (SR) Control.
  • Light-Load Efficiency Management Including.
  • Burst Mode Operation.
  • Discontinuous Conduction Mode (DCM), Dynamic SR On and Off Control with Programmable Threshold.
  • Programmable Adaptive Delay.
  • Average or Peak Current Mode Control With Programmable Slope Compensation and Voltage Mode Control.
  • Naturally Handles Pre-.
