UCC28780 - High Frequency Active Clamp Flyback Controller

General Description

UCC28780 is a high-frequency active-clamp flyback controller that enables high-density AC-to-DC power supplies that comply with stringent global efficiency standards such as DoE Level VI and EU CoC V5 Tier-2.

Key Features

  • 1 Full and Partial Zero Voltage Switching (ZVS) of Primary FET with Adaptive Control.
  • Programmable Timing for External Si or GaN FETs.
  • High Switching Frequency up to 1 MHz.
  • Programmable Adaptive Burst Control and Standby Mode for Light-Load Efficiency with Low Output Ripple and Audible Noise Mitigation.
  • Brownout Detection without Direct Line Sensing.
  • Accurate Programmable Over-Power Protection (OPP) to Support Peak Power Mode.
  • Fault.
