Why Choose STR-A6351?
- Integrated MOSFET + Controller - Reduces component count vs. discrete PWM controller + external MOSFET
- Quasi-Resonant Operation - Lower switching losses and EMI vs. hard-switching flyback
- 650V Drain Rating - Safe margin for 230V AC mains-connected LCD power supplies
- Built-in Startup - No external startup resistor chain needed
- Auto-Restart Protection - Automatically recovers from fault conditions
Typical Applications
- LCD monitor power supply repair (15-27 inch displays)
- LCD TV auxiliary power supply replacement
- Flyback converter design for display applications
- Industrial display power supply
FAQ
Q: How do I identify a failed STR-A6351? Common failure symptoms: no power output, blown fuse, shorted drain-source (measure with multimeter in diode mode). Replace with new STR-A6351 and check surrounding components (optocoupler, feedback resistors) before powering on.
Q: Is STR-A6351 the same as A6351A? Yes - A6351A is the short marking used on the IC body. Full part number is STR-A6351.
