ABSTRACT:
A detector circuit (301) is utilized in a DC to DC converter (300) having an inductor (356) coupled to a switch (358) for interrupting an electric current through the inductor (356), thereby allowing the inductor (356) to transfer stored energy to a capacitive load (364). The detector circuit (301) includes a capacitor (302) coupled to the inductor (356) for generating a transient current (428) in response to a completion of a transfer of stored energy from the inductor (356). The detector circuit (301) further includes a reference current generator (306) for generating a reference current, and a summing node (304) coupled to the capacitor (302) and coupled to the reference current generator (306) for summing the transient current (428) and the reference current. The two summed currents form a transient control current (436) responsive to the completion (424) of the transfer of stored energy from the inductor (356).
