Diodes Incorporated introduced two automotive LED drivers that combine robust performance, simplified design, and flexibility to address internal and external lighting applications, such as fog lamps, position lamps, rear lamps, and door lamps.
The AL8860Q and AL8861Q have a wide-operating voltage range from 4.5V to 40V to withstand load-dump events and operate correctly at low-cranking voltages in stop-start applications. Leveraging hysteretic-mode buck control simplifies the design of the feedback loop, enabling inherent stability with only four external components. Designers can save real estate and minimize the electronic bill of materials due to the integrated, main power MOSFET and a programmable switching frequency up to 1MHz that allows a small output inductor.
The devices can source 1.5A for powering loads up to 40W depending on supply voltage and external components (more info).
