The built-in frequency jittering function helps disperse electromagnetic interference, allowing for simpler and cheaper EMI filters in the final product.

Output regulation is achieved via optical feedback. An optocoupler connected to Pin 5 (FB) modifies the internal oscillator's duty cycle. By monitoring the feedback current, the controller adjusts the turn-off timing of the MOSFET to counteract load variations. 5. Built-in Protection Networks The STR-F6267, produced by Sanken Electric, is a
