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. A typical application for the AIC6600 is to drive LEDs with a constant current of 20m A or 30m A. Multiple AIC6600 can also be used in parallel to provide higher currents. 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. z T-8 CFL Replacement LED Solution z General Illumination - TYPICAL APPLICATION CIRCUIT AC Power D1 DIODE D3 DIODE U1 D2 D4 NC MAIN DIODE DIODE 5 VS1 VS2 LED LED Main String LED LED S1 LED S2 Analog Integrations Corporation Si-Soft Research Center 3A1, No.1, Li-Hsin Rd.
