Claim Text:
1. A regulator controller for coupling to a voltage source, an inductor and an output capacitor, said regulator controller comprising: an input terminal for coupling to the voltage source and for coupling to a first end of the inductor, wherein said input terminal develops an input voltage; an inductor terminal for coupling to a second end of the inductor; at least one output terminal including a first output terminal for coupling to the output capacitor, wherein said first output terminal develops an output voltage; a switching circuit coupled to the input terminal and the inductor terminal, wherein said switching circuit selectively couples said inductor terminal to ground during a charging period and to said at least one output terminal during a discharging period during a switching cycle; a switch control circuit coupled to said switching circuit, wherein said switch control circuit sets a duration of said charging period based on said input voltage and sets duration of said discharging period based on a difference between said input voltage and said output voltage; and a discontinuous detection circuit that terminates said switching cycle upon detection of a condition indicative of zero current through the inductor, wherein said condition indicative of zero current through the inductor comprises a voltage of said inductor terminal reaching a voltage level of said input terminal.
