Str F6267 Datasheet Pdf Updated [2021] Jun 2026

The STR-F6267 is a highly integrated off-line switching regulator IC manufactured by Sanken Electric Co., Ltd. This integrated circuit is specifically designed for use in Switching Mode Power Supply (SMPS) applications, where it provides efficient and reliable power regulation for a wide range of electronic devices. The IC combines a power MOSFET and a control circuit into a single package, simplifying power supply designs and reducing the overall component count.

Delivers inherent line-voltage ripple rejection and cycle-by-cycle peak current limiting.

In a standard flyback converter configuration, the STR-F6267 is implemented with minimal peripheral components.

Includes built-in thermal shutdown, soft start, and current limit circuits to prevent damage during fault conditions.

Yes, higher power ratings within the same family can often substitute lower ones. For example, the or STR-F6654 are sometimes used as heavy-duty replacements, but you must verify pin compatibility, switching frequencies, and electrical limits in the official datasheets before performing a swap. Why does my STR-F6267 run extremely hot? The STR-F6267 is a highly integrated off-line switching

To ensure optimal performance and reliability when using the STR-F6267, consider the following design guidelines:

) will often burn open. Always replace it with a flameproof resistor of the exact same value.

The 5-pin SIP package reduces the overall component count and saves valuable PCB real estate. Common Applications In a standard flyback converter configuration, the STR-F6267
