INTERIM DATA SHEET
OFF-LINE QUASI-RESONANT
The Series STR-F6600 is specifically designed to satisfy the require-
ments for increased integration and reliability in off-line quasi-resonant
Flyback Converters The series incorporates a primary control and drive
circuit with discrete avalanche-rated Power MOSFETs

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 VAC
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.
Dwg. PK-011-1
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 series is provided in a five-pin
overmolded TO-3P style package, affording dielectric isolation without
compromising thermal characteristics.
