We are happy to report that a revised and updated version of the STR-F6267 Datasheet (PDF) has just been released.

Here is what has changed in the new revision and why you need to download this version before your next repair job.

5. Protection Features

  1. Overcurrent Protection (OCP)

    • Pulse‑by‑pulse limiting using S pin voltage.
    • If OCP persists for a set period → auto restart (hiccup mode).

  2. Overload Protection (OLP)

    • Monitored via FB pin voltage.
    • FB > threshold for longer than tOLP → latch/restart.

  3. Overvoltage Protection (OVP)

    • On VCC pin. Shuts down when VCC > ~27.5V.

  4. Thermal Shutdown (TSD)

    • Prevents overheating. Auto recovery with hysteresis.

3. Absolute Maximum Ratings (Typical)

| Parameter | Value | Unit | |--------------------------|--------------|------| | Drain‑source voltage | 700 | V | | Drain current (pulsed) | ~8 (check) | A | | VCC voltage | 32 | V | | FB pin voltage | -0.3 to +7 | V | | Operating junction temp. | -20 to +125 | °C | | Storage temp. | -40 to +150 | °C | Blog Title: Power Supply Repair Just Got Easier:

⚠️ These are typical. The updated datasheet may show higher/lower ratings, especially for VCC OVP trip point.

Key Specs from the New PDF

Here is the "Cheat Sheet" data extracted from the fresh update:

  • Control Method: Quasi-Resonant (Low noise & high efficiency).
  • Operating Frequency: 19 kHz to 65 kHz (Auto-adjusted by load).
  • Built-in MOSFET: 630V (Rds(on) ~ 2.4Ω typical).
  • Protection Features: OLP (Overload), OCP (Pulse-by-pulse), TSD (Thermal Shutdown), and OVP (Latch mode).

6. Typical Application Circuit

A basic flyback converter using STR‑F6267 includes:

  • 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

Conclusion

The STR F6267 datasheet PDF updated is an essential resource for anyone maintaining or designing a robust quasi-resonant power supply. The key updates in recent revisions include clearer burst-mode specifications, refined OCP threshold values, and improved thermal modeling.

To get the most out of this IC:

  • 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.
