60-W GaN PFC flyback reference design


Design files


This reference design uses UCC28811 power factor correction (PFC) flyback controller to create an isolated 60-V output capable of 1-A loading while keeping input harmonic distortion low. The high efficiency of using LMG3411R150 GaN primary switch allows for compact size and low-temperature rise during operation.

  • Over 91% efficient at maximum output power
  • Compact 95-mm x 36-mm PCB area and 30-mm total maximum height
  • PFC control reduces peak input current
Output voltage options PMP22538.1
Vin (Min) (V) 120
