The STR-F6267 is housed in a 5-pin TO-3P package. It minimizes external component counts, allowing for compact power supply designs. Absolute Maximum Ratings 650V Drain Current ( IDcap I sub cap D ): 12A (Peak) / 4.5A (Continuous) Avalanche Energy Capability ( EAScap E sub cap A cap S end-sub ): Single pulse capability for transient protection Supply Voltage ( VCCcap V sub cap C cap C end-sub ): 35V Overcurrent Protection Terminal Voltage ( VOCPcap V sub cap O cap C cap P end-sub ): -0.5V to +5V Operating Temperature ( TOPcap T sub cap O cap P end-sub ): -20°C to +125°C Storage Temperature ( TSTGcap T sub cap S cap T cap G end-sub ): -40°C to +125°C Electrical Characteristics

| Protection | Trigger Condition | Action | | :--- | :--- | :--- | | | ( V_S/OCP ) > 0.72V per cycle | Pulse-by-pulse duty cycle reduction. | | Overload (OLP) | FB pin voltage > threshold for >50ms | Latch-off (requires VCC power cycle to reset). | | Overvoltage (OVP) | ( V_CC ) > 24V (due to aux winding failure) | Latch-off. | | Thermal Shutdown (TSD) | Junction temp > 140°C | Soft shutdown; auto-recovery when temp drops 50°C hysteresis. |

Available in a TO-3P (5-pin) or ZIP-5 package, designed for easy heat sink mounting. Comprehensive Protection Features

Ensures a gradual power-up sequence to prevent sudden current surges during startup. Pinout Configuration (5-Pin Package) Description GND Ground reference Vcc Power supply for the IC's internal logic FB Feedback pin for voltage regulation CS Current Sense input for over-current protection DRAIN Connected to the internal power MOSFET's drain str f6267 datasheet pdf

The is a reliable, if older, power supply IC. It is ideal for repairing classic CRT TVs, DVD power supplies, and industrial flyback converters from the 2000s. For new designs, use a modern IC like the STR-A6000 series or TOP26x family (higher efficiency, lower standby power). If you are repairing equipment, check the VCC capacitor and snubber diode first – they cause 70% of failures.

Provides stable, regulated power for LED lamps and fixtures.

In a standard flyback application circuit, the STR-F6267 manages energy transfer from the primary AC rectified line to the secondary output stage. | | Overload (OLP) | FB pin voltage

Typically housed in a 5-pin molded plastic package (TO-3P style with a heatsink attachment). 2. STR-F6267 Pin Configuration and Functions

Check the startup resistor connected to Pin 4. If it opens, the IC cannot boot. Also, check for a short circuit between Pin 1 (Drain) and Pin 2 (Source).

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