Power management device of a touchable control system

摘要

A power management device of a touchable control system includes a boost circuit, a storage circuit, a detection circuit and a loading circuit. The boost circuit has an output terminal and generates an output voltage. The storage circuit electrically connects to the output terminal of the boost circuit and stores the output voltage. The detection circuit electrically connects to the storage circuit so as to detect the output voltage. The loading circuit electrically connects or disconnects to the output terminal of the boost circuit according to a predetermined value of the output voltage.
