STRG6651 - Off-Line Quasi-Resonant Flyback Switching Regulator

Features

  • The device is provided in a five-pin over-molded TO-220 style package, affording dielectric isolation without compromising thermal characteristics. Two lead forms are available (with and without the suffix ‘-LF’) to accommodate printed wiring board layout or mechanical constraints. Proven in substantial volumes, the STR-G6651 is a robust low-risk solution for off-line power supplies particularly where management of EMI at the source is a significant element of the system design.
