Protection features: Overcurrent, Overvoltage, and Thermal shutdown. Pinout Configuration
The STR-F6267 typically uses a 5-pin layout. Understanding these pins is crucial for troubleshooting power supply failures: Pin # Description 1 Drain
MOSFET Drain; connects to the primary winding of the transformer. 2 Source
MOSFET Source; usually connects to ground via a current-sensing resistor. 3 Ground Control circuit ground. 4 VCC
Power supply for the internal control circuit (startup voltage). 5 Feedback
Regulation input; receives error signal from the optocoupler. Deep Troubleshooting Guide
If you are repairing a device using the STR-F6267, follow these common diagnostic steps:
Check Pin 4 (VCC): If the chip won't start, check the startup resistor connected to Pin 4. You should see a rising voltage (typically around 16V–18V) before the chip kicks in.
Inspect the "Source" Resistor: The small-ohm resistor connected to Pin 2 often blows if the MOSFET shorts. If this resistor is open, the IC is likely dead.
MOSFET Test: Use a multimeter to check for a short between Pin 1 (Drain) and Pin 2 (Source). A short here indicates internal catastrophic failure.
Secondary Side: If the IC is "pulsing" (voltage on VCC keeps rising and falling), check for a shorted diode on the secondary side of the power supply. Technical Resources
