AL8860Q Overview
Pin Assignments The AL8860Q 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 voltage from 4.5V to 40V and provide an externally adjustable output current up to 1.5A for MSOP8EP package. Depending upon supply voltage and external ponents, this...
