If the chip won't start, check the startup resistor connected to Pin 4. You should see a rising voltage (typically around 16V–18V) before the chip kicks in.

Includes built-in thermal shutdown (TSD), over-voltage protection (OVP), over-current protection (OCP), and soft-start functionality. str f6267 datasheet pdf updated

The STR-F6267 remains a reliable choice for flyback designs under 80W. However, do not rely on a decade-old printout. from Allegro or a verified distributor to get the latest thermal derating curves and PCB layout guidelines. If the chip won't start, check the startup
