These devices are specifically designed to meet the requirements
for increased integration and reliability in off-line flyback (STR-S6401)
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, under-
voltage 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.
