Abstract

A voltage converter circuit may include: a first input node; a second input node; a first output node; a second output node; one or more charge pumps that convert a first input voltage supplied to the first input node up to a first output voltage and convert a second input voltage supplied to the second input node down to a second output voltage; and a control circuit to control the one or more charge pumps according to two operational modes. In the first operation mode, the control circuit supplies the first input voltage to the first input node, leaves the second input node floating, and outputs the first output voltage at the first output node. In the second operation mode, the control circuit supplies the second input voltage to the second input node, leaves the first input node floating, and outputs the second output voltage at the second output node.

Dependent claims

A voltage converter circuit, comprising:

a first input node;
a second input node;
a first output node;
a second output node;
one or more charge pumps configured to convert a first input voltage supplied to the first input node up to a first output voltage and to convert a second input voltage supplied to the second input node down to a second output voltage;
