Abstract

A charge pump apparatus including a first charge pump system, a second charge pump system, a switch transistor, and a voltage regulation circuit is provided. The first charge pump system converts a first supply voltage into a first boost voltage. The second charge pump system converts a second supply voltage into a second boost voltage. The switch transistor is coupled to the first charge pump system and the second charge pump system, and outputs an output voltage according to the second boost voltage. The switch transistor includes a control terminal receiving the second boost voltage, a first terminal receiving the first boost voltage, and a second terminal outputting the output voltage. The voltage regulation circuit controls the second charge pump system according to the output voltage to adjust the second boost voltage so that the output voltage approaches to a target output value.
