Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design UCC28250 SLUSA29D – APRIL 2010 – REVISED AUGUST 2015 UCC28250 Advanced PWM Controller With Prebias Operation.

General Description

The UCC28250 PWM controller is designed for high power density applications that may have stringent prebiased start-up requirements.

The integrated synchronous rectifier control outputs target highefficiency and high-performance topologies such as half-bridge, full-bridge, interleaved forward, and pushpull.

The UCC27200 half-bridge drivers and UCC2732X MOSFET drivers used in conjunction with the UCC28250 provide a complete power converter solution.

Key Features

  • 1 Prebiased Start-up.
  • Synchronous Rectifier Control Outputs With Programmable Delays (Including Zero Delay Support).
  • Voltage Mode Control With Input Voltage FeedForward or Current Mode Control.
  • Primary or Secondary-Side Control.
  • 3.3-V, 1.5% Accurate Reference Output.
  • 1-MHz Capable Switching Frequency.
  • 1% Accurate Cycle-by-Cycle Overcurrent Protection with Matched Duty Cycle Outputs.
  • Programmable Soft-Start and Hiccup Restart.
