Boost LED Driver with 12V AC and driving 6LEDS at 320mA
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
This design uses a 12Vac input which is rectified and fed to a boost DC to DC Converter with constant current feedback loop for driving 6 series LEDs at 0.32A. Also implemented is a simple circuit to decode a dimming signal from a TRIAC. This dimming decoder circuit controls the dimming level of the LEDs.
