g n i h tors c t i a Sw egul R STR-W6754 Universal-Input/100 W Off-Line QuasiResonant Flyback Switching Regulator The STR-W6754 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
