DN05047/D, 230 Vac, Low-Cost, Dimmable, Three-Stage LED Driver Design Note
参考設計 著者: onsemi
DN05047/D, Design Circuit uses an innovative linear topology to meet and exceed the design requirements for LED lamps that operate on 230 Vac mains power. Its primary features are its low cost, phase-cut dimmability, compactness, high light output, efficiency, high power factor, and low THD. The circuit uses Constant Current Regulators (CCRs) to control the current through the LEDs and protect against overvoltage. The circuit is capable of operating at 50 or 60 Hz and at voltages from 80 to 255 Vac
