Constant voltage/constant current power supplies generate 12 V at 1-A output at 80% average efficiency with greater than 75% efficiency at 10% load and less than 30 mW (at 230 VAC) no load power. The design features primary side regulation (PSR) and integrated 700-V FET. With a low component count, this reference design can be used as general purpose power supply.
