StarChips Technology SCT2004S V01_03; Jun/12 4-Channel Constant Current Driver Product Description The SCT2004S is a four 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 200ns.
The PWM control is performed by connecting the PWM signal from system control unit to OE pin of the SCT2004S.
The full scale current value of each output is set by an external resistor connected to REXT pin.
The SCT2004S guarantees to endure maximum DC 24V at each output port.
Each output of SCT2004S can sink a constant current up to 180mA.
Users can simply shunt the outputs to get higher current driv...
