As of the latest updates (2024/2025), the STR-F6267 is not officially discontinued. However, Sanken has released newer series like the STR-F6300 and STR-X6700 which offer lower standby power (under 100mW) and higher integration. If you see an "EOL NOTICE" UPD for the STR-F6267, consider these drop-in alternatives:
Always check the Product Status section in the STR F6267 datasheet PDF for "Active," "NRND" (Not Recommended for New Designs), or "Obsolete."
If your power supply using STR-F6267 is dead or cycling, the datasheet’s protection section helps diagnose:
| Symptom | Likely Cause | Datasheet Check Point | Solution | |---------|--------------|------------------------|-----------| | VCC cycles between 8V and 15V | Startup circuit fails or OLP (Overload) triggered | Check UVLO on/off thresholds (typically 15V on, 8.5V off) | Replace startup resistor or check secondary short | | No output, drain pin shows 320V but IC not switching | VCC pin voltage <15V | Measure VCC pin voltage during operation | Auxiliary winding may be open | | IC heats up rapidly | Overcurrent or MOSFET Rds(on) degradation | Check OCP threshold voltage (0.7V typical) | Replace current sense resistor (0.47Ω) | | Random shutdown under load | Thermal shutdown (TSD) activated | TSD temperature >140°C (from datasheet) | Improve heatsinking or reduce ambient temperature |
