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 hyster-
esis, 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.

WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit
designs that embody these components must conform with applicable safety requirements. Precau-
tions must be taken to prevent accidental contact with power-line potentials. Do not connect
grounded test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
Recommended mounting hardware torque:
4.34 - 5.79 lbf•ft (6 – 8 kg•cm or 0.588 – 0.784 Nm).
Recommended silicone grease:
Dow Corning SC102, Toshiba YG6260, Shin-Etsu G746., or equivalent
