3A LED driver with integrated DC-DC converter for automotive applications
The new ALED6000 is a single-chip automotive LED driver with integrated DC/DC converter designed to source up to 3 A on a single strip LED and to operate with a wide input-voltage range of 4.5V to 61V, which makes it the ideal choice for automotive systems.
Housed in a HTSSOP16 Package, the ALED600 is suitable for exterior lighting such as daytime running lights, headlights, rear lights, stop lights, and turn signals, as well as interior lighting.
Evaluation board is also available to help developers consolidate their designs.
