The STR-S6707, STR-S6708, and STR-S6709 are specifically designed to meet the requirement for increased integration and reliability in off-line quasi-resonant flyback converters.
These devices incorporate the primary control and proportional drive circuit with a thirdgeneration 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.
