13.2W (4A) Isolated Flyback Converter Reference Design
Description
PMP10632 is an isolated flyback converter reference design using the LM5020-2 controller IC. The reference design accepts an input voltage of 36Vin to 75Vin (48Vin nominal) and provides an isolated output of 3.3Vout: capable of supplying 4A of continuous current to the load. The nominal switching frequency of the design is approximately 250 KHz. All tests for this report were performed at 36Vin: 48Vin: and 75Vin. The board is a 2-layer PCB with 1oz. copper.
