, commonly found in television and industrial power systems. It integrates a power MOSFET and a controller IC into a single TO-3P package to simplify circuit design. Veswin Electronics Core Specifications Package Type: TO-3P (5-pin). Main Function:
: The IC includes a startup circuit that eliminates the need for external startup resistors. This feature reduces component count and simplifies the design.
: The STR-F6267 incorporates a high-voltage power MOSFET directly into the IC package. This integration reduces external component count, simplifies board layout, and improves overall system reliability. The MOSFET has a breakdown voltage typically of 650V or higher, which is well-suited for off-line power supply applications. If you’d like, I can: Features a high-voltage

The STR-F6267 belongs to the STR-F6200 series of regulators. It is widely used in consumer electronics like CRT televisions, monitors, and audio power supplies due to its robust protection features and minimal external component requirements. Key Features Avalanche-energy guaranteed. Low Startup Current: Only maximum startup current.
), which is typically , the Under-Voltage Lockout circuit safely deactivates the drive output to prevent the power MOSFET from operating in an unstable linear region. Regulation Mechanism
Based on the most current technical documentation, the STR-F6267 offers a robust set of features that make it an excellent choice for modern power supply designs:
