Part Number STR-W6756
Description Universal-Input / 140W Off-Line Quasi-Resonant Flyback Switching Regulator
Feature g n i h tors c t i a Sw egul R STR-W675 6 Universal-Input/140 W Off-Line Quasi Resonant Flyback Switching Regulator Th e STR-W6756 is a quasi-resonant regulat or specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power s upplies.
It incorporates a primary cont rol and drive circuit with an avalanche -rated power MOSFET.
The regulator exhi bits 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 inc rease of operational frequency during l ight loads to .
