General Description

The DD231 is a 3-channel constant current LED driver.

It’s designed to operate as a constant-current sink to drive the LEDs with an external resistance in low power environment.

Because the DD231 directly determines output current by each channel in low Bit-to-Bit skew, it is ideal for driving LED whose light intensity is proportional to the current passing through them, not the voltage across their terminals.

Key Features

  • ․Constant Current Output, 5~30mA. ․Supply Voltage VDD is 3V to 5V. ․Bit-to-Bit : ± 3.0% (Max) @ IOUT = 5 ~ 30mA. ․Only Need One External Resistor, No Other External Parts. ․Small 6-Pin SOT26 Package.
