Abstract

A current output circuit includes a DC-DC power source, a current output unit, and a voltage detector. The DC-DC power source controls an output voltage. The current output unit operates at the output voltage of the DC-DC power source, generates a current signal based on a control instruction, and outputs the current signal to a load. The voltage detector holds the voltage of the load at the peak thereof and outputs the voltage of the load held at the peak to the DC-DC power source as a voltage signal. The DC-DC power source controls the output voltage on the basis of the voltage signal.
