The disclosed technology relates to a power supply circuit that utilizes a double-sided printed circuit board (PCB) that has a first surface and a second surface. The second surface is disposed opposite the first surface. Mounted on the first surface is a first power stage and a first inductor. Mounted on the second surface is a second power stage and a second inductor. The second power stage is disposed opposite the first power stage. The second inductor is disposed opposite the first inductor.

Mirrored voltage regulator for high-current applications and method the same

The disclosed technology relates to a power supply circuit that utilizes an integrated power module that has a first and second power converter disposed on opposite sides of an inductor core. The power supply circuit includes an inductor core comprising a plurality of nano-magnetic layers embedded within a printed circuit board, a first winding disposed on a first outer surface of the inductor core, a second winding disposed on a second outer surface of the inductor core, a first active layer disposed on an outer surface of the first winding, a second active layer disposed on an outer surface of the second winding, a first capacitor tile disposed on an outer surface of the first active layer, and a second capacitor tile disposed on an outer surface of the second active layer.

Double inductor integrated power module for high current applications

Embedded PCB (printed circuit board) is used for the packaging and assembly of a low profile power conversion system module that can be employed in space constrained environment of small computer/electronic systems. The low profile power conversion system module may include an embedded PCB, a power silicon device embedded within the PCB, a magnetic component which is either embedded within the PCB or disposed on the PCB, or input/output terminals disposed on the side of the embedded PCB. The embedded PCB and the magnetic component may be thin planar shaped to save vertical space. The low profile power conversion system module can be placed inside a cavity formed in the system PCB to save even more vertical space.

Low profile packaging and assembly of a power conversion system in modular form

A module stack includes a lower module, a middle module above the lower module, and an upper module above the middle module. The lower module has power stage control circuitry configured to convert a PWM input signal into phase driver control signals, and power stages to be controlled by the phase driver control signals, respectively. The middle module has phase inductors each having a respective winding and a respective magnetic core. The respective winding has one end joined to a respective one of the power stages in the lower module and another end joined to a common node in the middle module. The upper module has a current sense resistor that has one end joined to the common node in the middle module and another end joined to an output node in the upper module. Other embodiments are also described and claimed.
