  • Patent number: 11183934
    Abstract: Voltage converter inlay modules are provided for embedding within a package substrate, and are configured to supply power to a processor, or similar digital circuit, which is mounted to the package substrate. The package substrate is typically mounted to a circuit board, or similar. The circuit board provides high-voltage, low-current power to the voltage converter module which, in turn, provides low-voltage high-current power to the processor. The voltage converter inlay provides largely vertical current conduction from the circuit board to the processor, thereby reducing conduction losses incurred by lateral current conduction. The location of the voltage converter inlay between the circuit board and the microprocessor minimizes radiation of electromagnetic interference. The number of terminals allocated for providing power to the package substrate may be minimized due to the voltage converter inlay inputting fairly low levels of current.
