Abstract:
A half-bridge circuit can include a high-side HEMT, a high-side switch transistor, a low-side HEMT, and a low-side switch transistor. The die substrates of the HEMTs can be coupled to the sources of their corresponding switch transistors. In another aspect, a packaged electronic device for a half-bridge circuit can have a design that can use shorter connectors that help to reduce parasitic inductance and resistance. In a further aspect, a packaged electronic device for a half-bridge circuit can include more than one connection along the bottom of the package allows less lead connections along the periphery of the packaged electronic device and can allow for a smaller package.
