www.DataSheet4U.com STR-S6411 AND STR-S6411F OFF-LINE SWITCHING REGULATORS – WITH POWER MOSFET OUTPUT DRAIN 1 LATCH OSC. Data Sheet 28101.1 SOURCE 2 GATE POWER GROUND SOFT START OVER-CURRENT PROTECTION V IN 3 PWM + 4 + These devices are specifically designed to meet the requirements for increased integration and reliability in off-line flyback (STR-S6411) and forward (STR-S6411F) converters operating in a fixed-frequency PWM mode. Each device incorporates the primary control and drive circuits with an avalanche-rated high-voltage power MOSFET. Crucial system parameters such as switching frequency and maximum duty cycle are fixed during manufacture. The STR-S6411 and STR-S6411F differ only in their maximum duty cycle. Control circuit decoupling and layout are optimized within each device. Cycle-by-cycle and average-current limiting, soft start, undervoltage lockout with hysteresis, and thermal shutdown protect the device during all normal and overload conditions. The performance and reliability of these devices, and their variable-frequency counterparts, has been proven in substantial volume production. The requirements of high dielectric isolation and low transient thermal impedance and steady-state thermal resistance are satisfied in an over-molded, 9-pin single in-line power package. Dwg.
