Abstract:

A power converter sub-assembly/module includes a power switching assemblage defining a cavity within which can be mounted a driver IC. The power switching assemblage includes a load inductor component stack attached to a power transistor block and an interconnect spacer block, defining a cavity between the two blocks. The power transistor block includes a high and low side FETs attached side-by-side to a switch-node metal carrier that includes an attach-surface opposite the FETs. The power switching assemblage is mountable to an interconnect surface that includes connection pads VIN, VOUT, GND, HG (high-side gate) and LG low-side gate). For a module configuration, the power switching assemblage is combined with a driver IC that provides high (HG) and low (LG) gate drive—the power switching assemblage and the driver IC are mounted to a module interconnect substrate, with the driver IC mounted within the cavity of the power switching assemblage.
