Texas Instruments UCC28881DR | Demoboard TIDA-010250

UCC28881 700-V, 225-mA Low Quiescent Current Off-Line Converter

Overview

TopologyMotor Drive
Switching frequency52-75 kHz
IC revision00

Description

The UCC28881 integrates the controller and a 14-Ω, 700-V power MOSFET into one monolithic device. The device also integrates a high voltage current source, enabling start up and operation directly from the rectified mains voltage. UCC28881 is the same family device of UCC28880, with higher current handling capability.

Features

  • Integrated 14-Ω, 700-V Power MOSFET
  • Integrated High-Voltage Current Source for Internal Device Bias Power
  • Integrated Current Sense
  • Internal Soft Start
  • Self-Biased Switcher (Start Up and Operation Directly from Rectified Mains Voltage)
  • Supports Buck, Buck-Boost and Flyback Topologies
  • <100-μA Device Quiescent Current
  • Robust Current Protection During Load Short Circuit
  • Protection
  • Current Limit
  • Overload and Output Short Circuit
  • Over Temperature

Typical applications

  • AC-to-DC Power Supplies(Non-Isolated Buck Converter with Output Current up to 225 mA for CCM;150 mA for DCM), E-Meter, Home Automation SMPS, Bias Power for MCU, RF and IoT Enabled Devices
  • Appliances, White Goods and LED Drivers
