G6653 - 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. 28102.9A 2 1.

STR-G6651 Data Sheet OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATOR The STR-G6651 is specifically designed to satisfy the requirements for increased integration and reliability in off-line quasi-resonant flyback converters. This device incorporates the primary control and drive circuit with a discrete avalanche-rated power MOSFET. FDBK OSC. LATCH www.DataSheet4U.com UVLO OVP TSD GROUND OVERCURRENT & FEEDBACK SOURCE SUPPLY DRAIN Cycle-by-cycle current limiting, under-voltage lockout with hysteresis, over-voltage protection, and thermal shutdown protects the power supply during the normal overload and fault conditions. Over-voltage protection and thermal shutdown are latched after a short delay. The latch may be reset by cycling the input supply.
