DD233 DD233 4-CHANNEL CONSTANT CURRENT LED DRIVERS DESCRIPTION The DD233 is a 4-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 DD233 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. The ENABLE provides the low power stand by function for mobile applications. This configuration elim
