ABSTRACT:
A method of controlling the output voltage of a voltage regulator that uses a transimpedance block is disclosed. The method comprises measuring the voltage representative current of the output and comparing the voltage representative current to a reference current. Finally, the charging process is stopped if the voltage representative current of the secondary winding is substantially the same as the reference current.
