Abstract
A switching power converter circuit comprises a single inductive circuit element; a common control loop circuit coupled to a circuit input and the inductive circuit element and including switching circuit elements to charge the inductive circuit element using energy provided at the circuit input; at least one current sensing circuit configured to sense inductor current of the inductive circuit element; one or more output control loop circuits that each include switching circuit elements activated to generate an output voltage; and one or more pulse width modulation (PWM) circuits configured to generate a PWM control signal to activate the switching circuit elements of the output control loop circuits and to change a peak voltage of the PWM control signal of the one or more PWM circuits according to the inductor current.
