LM5017 Fly-Buck Quad Isolated Output Power Supply without Optocoupler

Fly-Buck Reference design uses the LM5017 buck regulator to generate four isolated outputs: 15V@50mA and 5V@100mA. The regulation is done on the primary side, and thus no Optocoupler is needed. The overall load/line regulation for each output is within +/-5%. The input voltage range is from 17V to 32V. It's suitable for applications requiring multiple positive and negative bias voltage rails
