STR-S6704 Datasheet | Allegro MicroSystems

STR-S6703 AND STR-S6704 OFF-LINE SWITCHING REGULATORS - WITH BIPOLAR SWITCHING TRANSISTOR COLLECTOR 1 FAULT The STR-S6703 and STR-S6704 are specifically designed to meet the requirement for increased integration and reliability in off-line quasiresonant flyback converters. These devices incorporate the primary control and proportional drive circuit with a third-generation high-voltage bipolar switching transistor. Crucial system parameters such as maximum ON time and OFF time are fixed during manufacture. Local control circuit decoupling and layout are optimized within each device. Cycle-by-cycle current limiting, under-voltage lock-out with hysteresis, over-voltage...
