Abstract
A rectifier circuit rectifies the current that flows through a reception coil. A smoothing capacitor is coupled to the output of the rectifier circuit. A power supply circuit stabilizes the rectified voltage VRECT that occurs across the smoothing capacitor, and supplies the rectified voltage thus stabilized to a load. A dump circuit sinks the first dump current IDUMP from the output of the power supply circuit. A current detection circuit detects the current IOUT that flows through the power supply circuit, and generates a current detection signal S11 that indicates the amount of the current.
