Abstract:To meet the power requirements of the vehicle multimedia system based on OMAP5912, a highreliable, lowcost and easycontrolled power management system based on TPS65010, TPS71501 and FDC6331L was proposed, and the specific circuit was given. The hardware and software designs for low power dissipation were proposed. The results of research show that the system illustrates a good prospect of application and extension.
