Abstract
A system for detecting current through a secondary winding of a switching voltage regulator without directly sensing the current through the secondary winding of the switching voltage regulator, the system including a diode; an inductor connected in series with the diode to form a current detection path, wherein the current detection path is connected in parallel with the secondary winding; a switching element connected in series with the current detection path and the secondary winding; and a controller operable to sense a voltage drop between a first terminal of the switching element and a second terminal of the diode, the voltage drop being indicative of the current through the secondary winding.
