such as televisions, monitors, and set-top boxes. Industrial SMPS circuits and LED drivers.
The STR-F6267 belongs to Sanken’s legacy family of SMPS primary controllers. It is engineered primarily for quasi-resonant or hard-switching flyback converters, operating directly from rectified AC mains voltage. str f6267 datasheet pdf upd
Features a high-voltage MOSFET capable of handling high power density 1.2.3.
The STR-F6267 is typically deployed in a flyback converter configuration, which is the standard design for low-to-medium power offline power supplies. controller, and a frequency jittering circuit to minimize
The DRAIN pin operates at high voltage (>400V). Ensure proper discharge before handling.
is a dependable offline switching regulator IC that combines an avalanche-guaranteed power MOSFET and advanced current-mode PWM controllers into a space-saving TO-3P package. It remains a widely utilized component for replacing and repairing television, audio, and legacy consumer electronics power supplies globally. If youg., universal 85V–265V or fixed 220V) Your requirements The DRAIN pin operates at high voltage (>400V)
Output voltage feedback travels across an isolation barrier via an optocoupler directly to the pin. The IC compares this voltage to an internal reference on a cycle-by-cycle basis, adjusting the MOSFET's conduction time ( TONcap T sub cap O cap N end-sub ) to maintain a constant output voltage. 4.
