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.
Low-current startup and a low-power standby mode selected from the secondary circuit completes a comprehensive suite of 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.
