8-Channel Constant Current Driver

Product Description

The SCT2008 is an eight channels constant current driver best for LED lighting. It provides the PWM

control effect by sinking constant current from LED clusters with minimum pulse width 80ns. The PWM

control is performed by connecting the PWM signal from system control unit to OE pin of the SCT2008.

The full scale current value of each output is set by an external resistor connected to REXT pin.

The SCT2008 guarantees to endure maximum DC 24V at each output port. Each output of SCT2008

can sink a constant current up to 160mA. Users can simply shunt the outputs to get higher current

driverꢀability, especially in the case of high power LED lighting.

The excellent current regulation capability allows SCT2008 easily drive each output current to a constant

stable output nearly without affected by power supply of LED, loading due to variant V_Fof LEDs and

operating temperature. The SCT2008 is equipped with negative temperature coefficient characteristics,

thus the driver system and LEDs are protected from damage of thermal runaway or overheated.
