DD231 3-CHANNEL CONSTANT CURRENT LED DRIVERS

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 w.
