AL8841Q - DIODES

AL8841Q AUTOMOTIVE 40V 1A/1.5A STEP-DOWN LED DQRIVER

Pin Assignments 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-8E.
