18-VDC - 30-VDC input multiple output flybuck reference design

This isolated flybuck reference design uses the LM3150 synchronous buck controller to generate one non-isolated output (3.3 V at 5 A) and two isolated outputs (5 V at 100 mA, 5 V at 100 mA) from a DC input (18 VDC - 30 VDC). The design can provide 17.5-W output power. Two additonal linear regulator (...)
