It is widely used in flyback converter power supplies for televisions and monitors because it integrates a high-voltage power MOSFET and a controller chip in a single package. Quick Technical Specs Manufacturer: Sanken Electric Co., Ltd. [3, 4] Package Type: TO-3P-5 (5-pin) or ZIP package [3, 4]
Key features you need to check in the datasheet: str f6267 datasheet pdf updated
Published: [Current Date]
- AC input → rectifier → bulk capacitor → transformer primary → Drain pin
- VCC supplied from auxiliary winding + startup resistor from bulk capacitor
- S pin → current sense resistor (Rsense) to GND
- FB pin → optocoupler + TL431 feedback from secondary side
- Snubber across primary winding (RCD or Zener) to limit drain voltage spikes
- Built‑in avalanche‑rugged MOSFET (700 V or 650 V, depending on version)
- Current‑mode control with leading‑edge blanking (LEB)
- Auto restart overcurrent protection (OCP)
- Pulse‑by‑pulse overcurrent limit
- Overload protection (OLP) with timer‑based latch
- Overvoltage protection (OVP) on VCC pin
- Thermal shutdown (TSD) with hysteresis
- Low startup current (typ. <20 µA)
- Burst mode operation at light load for low standby power
- Always follow the recommended layout in section 10 of the datasheet.
- Use a high-quality low-ESR capacitor on the VCC pin.
- Ensure your snubber network matches the 150W reference design.
