Product Description
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 ofthe 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
