7 Power module STR-G5653/6454R
The Series STR-G5653/F6654 is specifically designed to satisfy the requirements for increased
integration and reliability in off-line quasi-resonant flyback converters. The series incorporates a high-
precise error amplifying control and drive circuit with discrete avalanche-rated power MOSFET,
featuring fewer external components, small-size and standard power supply.
Covering the power range from below 25 watts up to 300 watts for 100/115/230 VAC inputs, and .up
to 150 watts for 85 to 265 VAG universal input, these devices can be used in a range of applications,
from battery chargers and set top boxes, to televisions, monitors, and industrial power supply units.
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. Low-
current startup and a low-power standby mode selected from the secondary circuit completes a
comprehensive suite of features. The series is provided in a five-pin over molded SIP style package,
affording dielectric isolation without compromising thermal characteristics.
