• Manufacturer Part Number: DD312
• Description: HIGH CONSTANT CURRENT LED DRIVER with ERROR DETECTION
• Manufacturer: SITI [Silicon Touch Technology Inc.]

DD312
General Description
LEDs. It incorporates a constant current circuitry with current value set by an external resistor. The
output enable terminal allows dimming control by system. The fast response of 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.
