• Description: HIGH CONSTANT CURRENT LED DRIVER
• Manufacturer: SITI [Silicon Touch Technology Inc.]

DD311
General Description
current switch, designed to drive power LEDs. It can provide a maximum sink current of 1A,
adjustable by reference current input. The output current is 100 times the input current value set by
an external resistor or bias voltage. The Maximum output voltage of 33V can provide more series
power LEDs in a string. The output enable allows dimming control or switching power applications.
