AL8861Q Overview
The AL8861Q is a hysteresis mode DC-DC step-down LED driver, designed for driving single or multiple series of the connected LEDs efficiently from a voltage source higher than the LED voltage. The device can operate with an input supply from 4.5V to 40V and provide an externally adjustable output current up to 1.5A for the MSOP-8EP package. Depending upon supply voltage and external ponents, this converter can...
