FAULT
The STR-S5707 and STR-S5708 are specifically designed to meet the requirement for increased integration and reliability in off-line quasiresonant flyback converters with indirect feedback. Each device incorporates 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.
