Abstract
A switching voltage converter is disclosed. The voltage converter includes a controller configured to generate first and second control signals, and a switch stack including six serially connected switches configured to receive a plurality of fixed voltages and the first and second control signals. The switch stack is configured to generate a voltage signal at a switch node based on the fixed voltages and on the control signals. In addition, the voltage signal is controlled to be substantially equal to a first fixed supply voltage or substantially equal to a second fixed supply voltage according to the first and second control signals, and an output filter connected to the switch node and configured to generate an output voltage based on the voltage at the switch node.
