3-Channel Constant Current Driver
Product Description
The SCT2001 is designed to drive multiple LEDs in series from a high input voltage rail. The SCT2001
contains three output channels which are regulated to sink constant current for driving LEDs of large
range VF variations.
In the field of LEDs driving applications, users can simply adjust the output current from 10 mA to 45 mA
through an external resistor RADJ to control the light intensity of LEDs. The SCT2001 guarantees to
endure maximum DC 24V at each output port.
Features
Three constant,current outputs rate at 24V
Constant current range:10 – 45mA
Wide operating operation by adding resistor from high rail to supply input
±2%(typ) current matching between outputs
±4%(typ) current matching between ICs
Smart dimming control via ADJ pin
Low drop,out output 0.3V@20mA
Excellent current regulation to load, supply voltage and temperature
All output current are adjusted through one external resistor
Hysteresis input for ADJ external resistor
Built,in power on reset and thermal protection function
Package: Small 2mmx2mm DFN and SOT,236
Applications: Mini light bar, LED backlight, LED lamp
