Description for the UCC28704EVM-724

The UCC28704EVM-724 is a 10-W off-line isolated power supply providing 5-V output on a USB-A port. The converter output voltage and current are regulated to 5% accuracy without using an optocoupler or secondary-side feedback circuits. The EVM demonstrates a low-cost solution to comply with global external power-supply efficiency standards (Department of Energy Level VI, EU Code of Conduct V5 Tier-2, etc.) without adding a secondary-side synchronous rectifier.
