F6600

The Series STR-F6600 is specifically designed to satisfy the requirementsfor increased integration and reliability in off-line quasi-resonantflyback converters. The series incorporates a primary control and drivecircuit with discrete avalanche-rated power MOSFETs.

Covering the power range from below 25 watts up to 300 watts for100/115/230 VAC inputs, and up to 150 watts for 85 to 265 VACuniversal input, these devices can be used in a range of applications,from battery chargers and set top boxes, to televisions, monitors, andindustrial power supply units.

Cycle-by-cycle current limiting, under-voltage lockout with hysteresis,over-voltage protection, and thermal shutdown protects the powersupply during the normal overload and fault conditions. Over-voltageprotection and thermal shutdown are latched after a short delay. Thelatch may be reset by cycling the input supply. Low-current startup anda low-power standby mode selected from the secondary circuit completesa comprehensive suite of features. The series is provided in a five-pinovermolded TO-3P style package, affording dielectric isolation withoutcompromising thermal characteristics.
