| STR-S6401 AND STR-S6401F OFF-LINE SWITCHING REGULATORS - WITH POWER MOSFET OUTPUT DRAIN 1 LATCH OSC. 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. 5 6 7 UVLO REF. SIGNAL GROUND FDBK 8 9 Dwg.

EK-003-1 STR-S6401 AND STR-S6401F OFF-LINE SWITCHING REGULATORS APPLICATIONS INFORMATION WARNING -- These devices are designed to be operated at lethal voltages and energy levels. Circuit designs that embody these components must conform with applicable safety requirements. Precautions must be taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment. The use of an isolation transformer is recommended during circuit development and breadboarding. The power MOSFET outputs of these devices are similar to the International Rectifier type IRFP448. These devices feature an excellent combination of fast switching, ruggedized device design, low on-resistance, and cost effectiveness. Recommended mounting hardware torque: 4.34 - 5.79 lbf*ft (6 - 8 kg*cm or 0.588 - 0.784 Nm).
