Abstract

A voltage converter for converting an input voltage to a different output voltage includes an output filter for providing the output voltage and a voltage switch coupled in series between the input voltage and the output filter. A controller compares the output voltage to a reference voltage and in response thereto, provides signals to turn the voltage switch on or off. A level shifter is coupled between the controller and the voltage switch.
