ABSTRACT:
A method for sensing the supply current of a switched DC-to-DC converter is discussed. The method sensing a first voltage that is proportional to the supply current, wherein the first voltage has first noise; outputting a second voltage that is based on the first voltage, and wherein the second voltage has second noise that is smaller than the first noise; and comparing the second voltage to a reference voltage to provide an indication of the supply current. According to the systems and methods disclosed herein, accurate current sensing is provided.
