This reference design implements an automotive power supply solution for use in analog gauge clusters, hybrid clusters and cluster display systems. It provides 5 volt, 3.3 volt and 1.2 volt outputs suitable for powering all subsystems within an automotive instrument cluster, a cluster display, or an automotive remote touch display.
