Description
General part information
AL8841Q Series
The AL8841Q is a hysteresis mode DC-DC step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device can operate from an input supply between 4.5V and 40V and provide an externally adjustable output current up to 1A for TSOT25 and 1.5A for MSOP-8EP package. Depending upon supply voltage and external components, this converter can provide up to 60W of output power.
