Abstract: An apparatus includes a direct-current to direct-current (DC-DC) converter having an output terminal and at least one electronic switch. The DC-DC converter also includes: 1) a first feedback loop configured to control a voltage at the output terminal by adjusting a first switching parameter of the at least one electronic switch; and 2) a second feedback loop configured to adjust a second switching parameter of the at least one electronic switch. The second feedback loop includes a switched-capacitor circuit configured to determine a threshold signal based on an error between a reference signal and a control signal for the at least one electronic switch. The second feedback loop is configured to adjust the second switching parameter based on a comparison of an on-time signal with the threshold signal.

Abstract: A packaged integrated circuit (IC) includes a package substrate, an electronic device on the package substrate, and metal interconnects coupled between the electronic device and the package substrate. The packaged IC also includes an insulation material on the package substrate and encapsulating the electronic device. The insulation material surrounds the metal interconnects. An inductor is over the electronic device and is coupled to the package substrate. A magnetic material is on the insulation material and encapsulates the inductor. The magnetic material is different from the insulation material.
