Abstract:
A rearview mirror assembly for a vehicle, comprising:a mirror mounting structure including a housing and a mounting bracket adapted for mounting to a vehicle; an electrochromic mirror mounted in said housing; a linear pre-regulator circuit coupled to a vehicle power source for reducing transients in the power received from the vehicle power source; a switched power supply coupled to an output of said linear pre-regulator circuit for reducing the voltage of the power supplied from the vehicle power source; and a control circuit coupled to said switched power supply to receive the reduced voltage power output from said switched power supply, said control circuit controls the reflectance of the electrochromic mirror by varying the voltage applied to the electrochromic mirror, wherein said linear pre-regulator circuit, said switched power supply, and said control circuit are associated with said mirror mounting structure.
