A power module has a printed circuit board (PCB) having an output inductor substrate layer and an output capacitor substrate layer. Power converters of the power module are implemented using monolithic integrated circuit (IC) switch blocks that are mounted on a surface of the power module. Output voltages of the power converters are provided at output voltage nodes. The power converters include output inductors that are embedded within the output inductor substrate layer and output capacitors that are embedded within the output capacitor substrate layer. Embedded output inductors and capacitors are connected to corresponding output voltage nodes.

Power module with output inductors and output capacitors that are embedded within substrate layers

A power module has a substrate with a bottom side and a component side. Power converters of the power module are implemented using monolithic integrated circuit (IC) switch blocks that are mounted on the component side of the substrate. The power converters include output inductors that are disposed within the substrate. An end of an output inductor is connected to a switch node of a monolithic IC switch block and another end of the output inductor is connected to an output voltage node of the power module.
