3-CHANNEL HIGH CONSTANT CURRENT LED DRIVER
with ERROR DETECTION
General Description
DD313 is a high constant current driver designed for power LED applications. It incorporates
three-channel constant current circuitry with current value set by three external resistors. The three
enable pins are specifically designed for independent control over each of the three output terminals.
The fast response of the output current can adapt to high dimming resolution and high refresh rate
applications. Built-in LED open detection, over temperature, and over current protection functions
ensure the system reliability.
