- DESCRIPTION
- The AIC6634 is an off-line linear LED driver. The application of high bright LED is widely used for general illumination.
The AIC6634 can drive a plurality of LED strings. 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 ±10% variations. A typical application for the AIC6634 is to drive LEDs with a constant current of 50mA ~ 100mA. Multiple AIC6634 can also be used in parallel to provide higher currents.
The AIC6634 is available in a SOP-16 exposed pad (150 mil) & TSSOP16 exposed pad package.
