Introduction

AI Translation

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 components, this converter can provide up to 40W of output power. The AL8861Q integrates the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Dimming can be realized by applying an external control signal to the VSET pin. The VSET pin will accept either a DC voltage signal or a PWM (pulse-width modulation) signal. The soft-start time can be adjusted by an external capacitor from the VSET pin to the ground. Applying a voltage of 0.2V or lower to the VSET pin can turn off the output and make the device enter into standby state with low power consumption. The AL8861Q is qualified to AEC-Q100 Grade 1 and is automotive grade to support PPAPs.
