Abstract
A power supply package is disclosed, including a power management integrated circuit (PMIC) die with a plurality of switching circuits, and a plurality of integrated 3-dimensional (3D) inductors disposed around the PMIC die. Each 3D inductor corresponds to a switching circuit and is electrically coupled to first and second connections for the corresponding switching circuit. An integrated electromagnetic interference (EMI) shield is disposed between the PMIC and the 3D inductors.
