Compact isolated DC/DC flyback reference design

This reference design uses LM5022-Q1 to make an isolated 3.3-V output capable of 1.1-A from a 9-V to 15-V input. All components are placed on one side of the board to reduce assembly complexity and cost. A secondary filter reduces the output ripple to under 30-mV peak-to-peak. The design can achieve (...)
