DD311 HIGH CONSTANT CURRENT LED DRIVER 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. 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.
Features
Maximum output current: 1A (determined by input reference current) Minimum output voltage: 1V (Iout = 1A) Maximum output voltage: 33V (output leakage current < 0.1uA) Maximum output enable frequency: 1MHz Excellent output current accuracy
Applications
LED architectural or entertainment lighting LED general or specialty illumination LED backlighting applications
Package Types
TO-252
HIGH CONSTANT CURRENT LED DRIVER Version:PRE.001
