Description :
The STR-W6753 is a quasi-resonant regulator specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power supplies. It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET. The regulator exhibits only low-level high-frequency EMI noise because of soft switching of the MOSFET close to ground (bottom point). A bottom-skip function minimizes an increase of operational frequency during light loads to improve system efficiency over the entire load range.

Features
▪ Quasi-resonant topology IC => Low EMI noise and soft switching
▪ Bottom-skip mode => Improved system efficiency over the entire output load by avoiding increase of switching frequency
▪ Auto-Standby mode => Lowers input power at very light output load condition
