Features

  • CCM-TCM multimode control in each AC half cycle. Light load efficiency is improved up to 2%
  • TI GaN with integrated zero current sensing
  • Single current sensor for both PFC control and e-metering with < 0.5% accuracy
  • Includes baby boost to extend holdup time and reduce bulk capacitor
  • Re-rush current control when AC comes back from dropout
