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.

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. 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.
