Single Channel High Power Constant Current Driver

Product Description

The SCT2301 is a single channel constant current driver best for the high power LED lighting and lamp

application. It provides the PWM control effect by sinking constant current from high power 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 SCT2301. The full scale current value of output is set by an external

resistor connected to REXT pin. The SCT2301 guarantees to endure maximum DC 24V at output port.

The output of SCT2301 can sink a constant current up to 720mA.

The excellent current regulation capability allows SCT2301 easily to 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 SCT2301 is equipped with over temperature protection. The single

channel IC stops driving the output while sensing its junction temperature exceeding 160°C the higher

limit and the output will be reactivated while the junction temperature is below 110°C. The exposed pad

on IC provides significant power dissipation. This provides lower thermal impedance from the IC to the

ambient air, thus IC can be operated more safely. In conclusion, the driver system is protected from

damage of overheated.
