Overview

UCC25640EVM-020 is a 180W, LLC resonant converter using UCC256404. This EVM accepts DC input from 360V to 410V, AC input voltage from 85VAC to 264VAC and outputs 12VDC with 180W full load output power.

Features
  • Optimized burst mode function for low audible noise and low standby power
  • Integrated high voltage startup and integrated gate drivers reducing total BOM count
  • Robust protection features including overvoltage, overcurrent and zero current switching detection
  • X capacitor discharge function

  • General Texas Instruments High Voltage Evaluation (TI_HV_EVM)
