UCC28740, Constant-Current Flyback Controller
The UCC28740 isolated-flyback power-supply controller provides Constant-Voltage (CV) using an optical coupler to improve transient response to largeload steps.
Constant-Current (CC) regulation is accomplished through Primary-Side Regulation (PSR) techniques.
This device processes information from op
