Direct voltage converter has switches connecting electrodes of charge pump capacitors not connected to output to intermediate stage outputs and/or to input voltage to maximize efficiency

摘要

The device operates on the principle of a charge pump, is regulated to a defined output voltage and has elementary stages, each with a charge pump capacitor and controlled switches. Switches connect electrodes of charge pump capacitors not connected to the output of the converter to one or more outputs of intermediate stages and/or to the input voltage. The switches are controlled by a control circuit to maximize the converter efficiency.
