Abstract
Power supply units of multiple channels each include an output stage that generates an output voltage across positive/negative outputs OUTP and OUTN, and a voltage detector that generates a voltage detection signal that indicates the output voltage. A feedback signal generating unit of the power supply unit of a master channel that is one of the multiple channels receives voltage detection signals from the power supply units of the remaining multiple channels, i.e., the slave channels, and generates a feedback signal based on the voltage detection signals of all the channels. A feedback controller generates a control signal such that the feedback signal approaches a target value. An output stage of each slave channel operates based on the control signal generated by the master channel.
