To successfully use or repair a circuit based on the STR-F6267:

Found in various industrial controllers and older computer monitors. Troubleshooting and Replacement The is a highly efficient, off-line switching regulator

In a standard TV or monitor power supply, the STR-F6267 operates as follows:

Sanken periodically revises datasheets. For example:

But F6267 was a master of discipline. Using its internal power MOSFET, it caught the surge, chopping it into precise pulses with its quasi-resonant rhythm. It worked in the shadows, regulating the flow with up to 95% efficiency, ensuring that every LED glowed with the exact brightness it needed. When things got too hot, its thermal shutdown would calmly step in, acting as a tireless bodyguard for the machine. Combining a high-voltage power MOSFET, a current-mode PWM

Regulates the output voltage via an optocoupler.
