Product Descriptions

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.
