ZHCSHY7A April 2018 – May 2018 UCC28742
PRODUCTION DATA.
The UCC28742 device is an SSR controller optimized for isolated-flyback AC-to-DC power supply applications, typically in the range from 5 W to 50 W, providing constant-voltage (CV) mode control using optocoupler based feedback. Its advanced control provides high performance operation. The device uses the information obtained from auxiliary winding sensing (VS) to make an accurate output current limit with time delayed output voltage shutdown and auto-start retry.
