Datasheet Pdf: Str F6267

This IC is frequently used in power supplies for consumer electronics, including:

Power MOSFET, current-mode PWM controller, and frequency jittering circuit Operating Temperature: Reliable operation up to 105 raised to the composed with power C AliExpress Pinout Configuration (5-Pin TO-3P/SIP)

A typical application circuit diagram, available in the official datasheet, will show the STR-F6267 connected to a flyback transformer, an optocoupler for feedback, and a few passive components like resistors and capacitors. The circuit usually includes an AC input rectifier, a bulk capacitor, and the output rectification stage. The IC's internal oscillator and control logic manage the switching of the MOSFET to regulate the output voltage based on the feedback signal.

In a standard flyback application circuit, the STR-F6267 manages energy transfer from the primary AC rectified line to the secondary output stage. This IC is frequently used in power supplies

The is an integrated circuit (IC) manufactured by Sanken Electric Co. It is primarily used as an off-line switching regulator in power supply circuits for consumer electronics like televisions and AC adapters. 📋 Technical Overview

The STR-F6267 is typically housed in a 5-pin TO-3PF molded package, designed for effective heat dissipation when attached to a heatsink. Pin Number Function Description Drain (D)

The STR-F6267 features built-in frequency jittering. By slightly shifting the switching frequency back and forth over a set range, the IC spreads peak EMI energy across a wider bandwidth, drastically easing compliance with strict RF noise standards.

— The reference ground pin for the internal low-voltage control circuitry.

Feedback terminal. Evaluates constant voltage constraints from secondary optocouplers.

Automatically powers down the device if internal temperatures exceed safe limits. Common Applications

A Resistor-Capacitor-Diode (RCD) snubber network must be placed across the transformer primary winding. This limits the leakage inductance voltage spike when the internal MOSFET turns off, protecting Pin 1 from exceeding 650V.
