Beschreibung
Zusammenfassung:	Various embodiments herein provide a switched capacitor voltage converter with a subset of one or more phases that selectively provide a decoupling capacitance. The voltage converter may include multiple phases coupled in parallel between an input terminal and an output terminal. The individual phases may include a capacitor and a set of switches. A first subset of one or more of the phases may operate in a switching mode in which the respective set of switches open and close to generate an output voltage at the output terminal based on an input voltage at the input terminal. The voltage converter may further include a second subset of one or more phases that are selectively operable in the switching mode or in a decoupling mode. In the decoupling mode, the switches of the respective phase may maintain the capacitor coupled between the output terminal and ground. Other embodiments may be described and claimed.
