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.
Features
z Maximum output current: 1A (determined by input reference current)
z Minimum output voltage: 1V (Iout = 1A)
z Maximum output voltage: 36V (output leakage current < 0.1uA)
z Maximum output enable frequency: 1MHz
z Excellent output current accuracy
Applications
z LED architectural or entertainment lighting
z LED general or specialty illumination
z LED backlighting applications
Package Types
z TO-252
