16-Channel Constant Current Driver

Product Description

The SCT2016S is a sixteen channels constant current driver best for the 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 SCT2016S. The full scale current value

of each output is set by an external resistor connected to REXT pin.

The SCT2016S guarantees to endure maximum DC 24V at each output port. Each

output of SCT2016S can sink a constant current up to 45mA. Users can simply shunt

the outputs to get higher current driver-ability, especially in the case of high power LED

lighting.

The excellent current regulation capability allows SCT2016S 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 SCT2016S is

equipped with over temperature protection. The sixteen channels IC stops driving the

output while sense its junction temperature exceeds the 160°C high limit and the

output will be reactivated while the junction temperature is below the 110°C low limit. In

conclusion, the driver system is protected from damage of overheated. Furthermore,

with wide operating range, the SCT2016S can be applied to lower input supply system.
