Str F6267 Datasheet Pdf Instant

For troubleshooting, a common practice is to disconnect the load (e.g., the horizontal output transistor) and connect a dummy load (like a 60W incandescent lamp) to the main B+ output. If the lamp lights up and the B+ voltage is present and stable, the STR-F6267 is likely functional, and the fault lies elsewhere in the secondary circuits.

The Sanken STR-F6267 is a powerful and efficient solution for offline switching power supplies, especially in quasi-resonant designs. Its high level of integration, combining a power MOSFET, control logic, and protection features, allows for reliable and compact power supply units.

Includes built-in Overcurrent Protection (OCP), Overvoltage Protection (OVP), and Thermal Shutdown (TSD).
