UCC28911 Datasheet High-voltage Flyback Switcher

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity UCC28910 UCC28911 SLUS769D – JULY 2013 – REVISED DECEMBER 2016 UCC28910, UCC28911 High-Voltage Flyback Switcher with Primary-Side.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The UCC28910 and UCC28911 are high-voltage flyback switchers that provide output voltage and current regulation without the use of an optical coupler.

Both devices incorporate a 700-V power FET and a controller that process operating information from the flyback auxiliary winding and power FET to provide a precise output voltage and current control.

The integrated high-voltage current source for startup that is switched off during device operation, and the controller current consumption is dynamically adjusted with load.

Key Features

  • 1 Constant-Voltage (CV) and Constant-Current (CC) Output Regulation Without Optical-Coupler.
  • ±5% Output Voltage Regulation Accuracy.
  • ±5% Output Current Regulation With AC Line and Primary Inductance Tolerance Compensation.
  • 700-V Start-Up and Smart Power Management Enables.
