Data Sheet 28101 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-S6401) and forward (STR-S6401F) converters operating in a fixed-frequency PWM mode.
Each device incorporates the primary control and drive circuits with an avalanche-rated power MOSFET.
Crucial system parameters such as switching frequency and maximum duty cycle are fixed during manufacture.
The STR-S6401 and STR-S6401F 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.
Similar off-line switching regulators, with output ratings to 800 V at 5 A, are also available.
