Original Abstract Submitted
A programmable switch converter controller for a power stage with a switch, an inductor, and a diode, includes a pulse-width modulator. The pulse-width modulator is configured to: generate an on-time interval (Ton) that is fixed or proportional to a demand signal proportional to a load adapted to be coupled to an output of the power stage; generate an off-time interval (Toff) that is inversely proportional to the product of a voltage across the inductor while the switch is off and a demand signal proportional to the load; initiate Ton when Toff elapses; and initiate Ton responsive to an external trigger signal.
