A quasi-resonant primary-side regulated isolated Flyback is used to provide 12V @ 1A from universal input voltage (90Vac to 264Vac). The converter does not employ any optocoupler and regulates the output voltage by sensing the auxiliary winding on primary side. A peak input voltage detector is used to sense input AC voltage, delivering 1/100 AC RMS equivalent voltage, with a +/-5% precision.
- Simple isolated PSR Flyback converter with integrated 700V FET
- Compact solution ("L" shaped PCB) supplies 12W with almost flat efficiency from 50mA to 1A load (75%...84%)
- Opto-less topology increases the reliability of the power supply
- Good output voltage regulation versus load: +/-5% in the whole temperature range
