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.

Key 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.
