Abstract
A switched-capacitor voltage converter including a switched-capacitor voltage conversion circuit, a loop regulator circuit, a first clamp transistor, a second clamp transistor, a first clamp circuit, and a second clamp circuit is provided. The loop regulator circuit is configured to monitor electrical parameters of any one or both of an input terminal and an output terminal of the switched-capacitor voltage converter, and output a voltage to a gate of the first clamp transistor or the second clamp transistor according to one or more electrical parameters to stabilize the one or more electrical parameters at their corresponding target values. According to the present disclosure, the loop regulator circuit is additionally configured in the switched-capacitor voltage converter, and two back-to-back clamp transistors are disposed between the input terminal and a reference terminal of the switched-capacitor voltage converter.
