SM8616AN

High Power

The SM8616AN is an off-line linear LED constant power driver. The application of high bright LED is widely used for general illumination.

The SM8616AN can drive a plurality of LED strings. When the voltage detecting circuit detects the different voltage level of input voltage, SM8616AN can auto switch the LED work strings. If the input voltage is lower than the Vf of the LED string that it will bypass the LED string. And turn on all LED strings when the input voltage is higher than the Vf of total LED strings. The number of LEDs in LED array is dependent on the voltage level of the AC power source that includes of ±10V variations. A typical application for the SM8616AN is to drive LEDs with a constant power of 10W to 50W for 100~120Vac input, and 10W to 100W for 200~240Vac input, which depend on the setting current.
