Preliminary AIC6600 Flexible Voltage Detect for LED Driver FEATURES DESCRIPTION Flexible Voltage Detect. Wide Range, Programmable LED Voltage. LED Thermal Regulation. Fixed Current Operation: 20mA or 30mA. 3V to 80V Supply Voltage Range. Low Quiescent Current. High Efficiency. LED Brightness Stable. No External Component. User TRIAC Dimming Control. SOP-8 Package. The AIC6600 is flexible voltage detect method of LED driver. The application of high bright LED is widely used for general illumination. The AIC6600 driving device includes a plurality of LEDs. When the voltage detecting circuit detects the different voltage level of input voltage, it can control the LED strings. If the input voltage is lower that it will bypass some LED strings. And turn on all LED strings when the input voltage is higher. The number of LEDs in LED array is dependent on the voltage level of the AC power source, that includes of ±15% variations. The quality of fixed current and wide range voltage makes this device ideal for TRIAC dimming applications. The AIC6600 is available in a SOP-8 package.
