Technology

SCT2001 V02_03; May/13

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 constantꢀcurrent 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 dropꢀout 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

Builtꢀin power on reset and thermal protection function

Package: Small 2mmx2mm DFN and SOTꢀ236

Applications: Mini light bar, LED backlight, LED lamp
