Description
The STR-S6707, STR-S6708, and STR-S6709 are IC chips designed for high integration and reliability in off-line quasi-resonant flyback converters. These devices integrate the primary control and proportional drive circuit with a third generation high-voltage bipolar switching transistor. They are equipped with local control circuit decoupling and optimized layout for each device. Additionally, cycle-by-cycle current limiting, under-voltage lock-out, over-voltage protection, and thermal shutdown provide protection during all normal and overload conditions. The versatile triple-level inhibit circuit includes OFF time synchronization required to establish quasi-resonant operation. Finally, the dual requirements of dielectric isolation and low transient thermal impedance and steady-state thermal resistance are satisfied in an over molded single-in-line power package.
