Abstract

A voltage doubler circuit configuration includes a switching regulator having a variable input voltage and a regulated voltage, and a voltage doubler circuit that utilizes the regulated voltage of the switching regulator. The voltage doubler circuit includes an output capacitor that receives an elevated voltage from a voltage doubler capacitor and an electrical clamp that limits the voltage doubler capacitor from exceeding the regulated voltage. The output voltage is twice the regulated voltage minus circuit losses.
