A VOLTAGE CONVERTER CIRCUIT

摘要

PURPOSE: A voltage converter circuit is provided to be used for a switching control by sensing a voltage signal in the front end of a functional component. CONSTITUTION: An input unit receives a first voltage signal. A coil(104) is serially connected to the input unit. A switching device(106) is directly connected to the coil. The switching device performs a switching operation according to a control signal. The signal output unit has an output terminal and is combined with the coil and the switching device. The signal output unit provides a second voltage signal to the output terminal according to the switching operation. A capacitor(102) is connected between the input unit and the output terminal.
