HIGH CONSTANT CURRENT LED DRIVER

DD311

General Description

DD311 is a single-channel constant current LED driver, which incorporates current mirror and

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. Tuning or enabling the bias voltage can provide dot correction or

global brightness control in LEDs system. The Maximum output voltage of 36V can provide more

series power LEDs in a string. The output enable allows dimming control applications.
