Description

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 a LMG3411R150 GaN primary switch allows for compact solution size and low temperature rise during operation.
