Description

180-VAC - 264-VAC input multiple output flyback reference designThis offline flyback reference design uses the UCC28740 controller to generate 3 isolated outputs (5 V at 30 mA, 15 V at 20 mA, 15 V at 20 mA) from an AC input (180 VAC - 264 VAC). The design can provide 750-mW output power. The UCC28740 uses an optical coupler to regulate the 5-V output and to improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high.

Features

180 VAC - 264 VAC input to 3 isolated outputsValley-switching operation for highest overall efficiencyOptocoupled feedback for constant voltage regulation
