A circuit converts an input voltage to an output voltage. The circuit includes a first stage voltage converter that receives the input voltage and converts the input voltage. The first stage voltage converter includes a first buck converter having a double rail output: a first rail at a high intermediate voltage and a second rail at a low intermediate voltage. The circuit also includes a second stage voltage converter that receives the output rails and produces the output voltage.
