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...
