STRG6653 - OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATOR

Download the STRG6653 datasheet PDF. This datasheet also covers the STR-G6653 variant, as both devices belong to the same off-line quasi-resonant flyback switching regulator family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The device is provided in a five-pin over-molded TO-220 style package, affording dielectric isolation without compromising thermal characteristics. Proven in substantial volumes, the STR-G6653 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.

Data Sheet 28102.9* STR-G6653 GROUND 3 SUPPLY 4 OSC. FDBK LATCH VIN OCP UVLO OVP TSD 5 OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATOR The STR-G6653 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. 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.
