Str F6267 Datasheet Pdf Updated File

From real-world repair logs (TV power boards like the 32” brand models using STR-F6267), here are the top 3 issues:

Monitors the source current on a pulse-by-pulse basis using an external resistor attached between Pin 2 and the primary ground. If the voltage drop across the resistor reaches the threshold limit, the conduction cycle is aborted instantly. Overvoltage Protection (OVP): Monitors the VCCcap V sub cap C cap C end-sub

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

| Pin Number | Name/Function | Description | | :--- | :--- | :--- | | | GND / Source | Ground reference for the control circuit and the source connection of the internal power MOSFET. | | 2 | VCC | Power supply pin for the IC. Provides operating voltage for the internal control logic. Requires a stabilizing capacitor. | | 3 | FB / Feedback | Feedback input pin. Connects to the secondary side via an optocoupler to regulate the output voltage. | | 4 | CS / Current Sense | Current Sense pin. Monitors the primary current via an external sense resistor. Used for overcurrent protection and feedback control. | | 5 | DRAIN | Drain pin of the internal high-voltage MOSFET. Connects to the primary side of the switching transformer. | str f6267 datasheet pdf updated
