Description

The AS1111x family are high efficient LED drivers designed to match current source bias for any color LED, including white and blue. The devices can drive up to 4 high-current LEDs, the LED current can be adjusted using an external resistor (RSET) and dimmed with an external PWM signal via pin EN. It only requires 150mV headroom voltage to operate and when the devices are disabled, the supply current drops down to less than 1µA.
