Patent ID: 7208928

Claim:
A power converter with input terminals for coupling to an energy source and output terminals for coupling to a load device, the power converter comprising: an output stage for selectively coupling the input terminals to the output terminals to deliver energy from an energy source to a load device; a controller operably coupled to the output stage for dynamically controlling said selective coupling of the input and output terminals; the output stage further characterized by an inductive element coupled to the input terminals, a capacitive element coupled to the output terminals, a MOSFET synchronous rectifying in element having a channel that conducts in the reverse direction, the rectifying element being closingly responsive to a first state and openly responsive to a second state, and a switch responsive to a control signal from the controller, the rectifying element and the switch being operably coupled with respect to said inductive and capacitive elements for causing the inductive element to be coupled to the capacitive element to discharge energy therefrom into the capacitive element by operably forming a series connected circuit of the power source, the inductive element and the capacitive element during the first state and causing the inductive element to be energized by operably forming a series connected circuit of the power source, the inductive element and the switch during the second state; the controller being responsive to input signals for selectively and non-oscillatorily generating the control signal to open the switch in said first state and close the switch in said second state, the input signals to the controller including an input voltage across the input terminals, and at least one of an output voltage across the output terminals, a selectable reference voltage and a feedback signal measured with respect to the inductive element.
