This 10-W non-isolated flyback reference design uses the UCC28742 controller to generate four outputs (5 V at 150 mA, 12 V at 690 mA, 15 V at 80 mA, 18 V at 20 mA). The controller provides constant-voltage and constant-current regulation. Transistors are used in place of an optocoupler feedback circuit to reduce the overall BOM cost.
