Abstract
A down-converted voltage regulator is provided. The first energy storage element provides a pre-charged voltage between a connection terminal and a ground terminal during the first phase. The second energy storage element has a first terminal, and it has a second terminal coupled to the output terminal of the voltage regulator. The third energy storage element is coupled between the output terminal of the voltage regulator and the ground terminal. During the first phase, the first terminal of the second energy storage element is coupled to the first energy storage element through the connection terminal to receive the pre-charged voltage. During the second phase, the first energy storage element is coupled between the input terminal and the output terminal of the voltage regulator to be pre-charged to store the pre-charged voltage, and the first terminal of the second energy storage element is coupled to the ground terminal.
