More Information
Summary:Techniques for integrating DC-DC power converters with other on-chip circuitry are provided. In one aspect, an integrated DC-DC power converter includes: a GaN transistor chip having at least one GaN switch formed thereon; an interposer chip, bonded to the GaN transistor chip, having at least one power driver transistor formed thereon; TSVs present in the interposer chip adjacent to the power driver transistor and which connect the power driver transistor to the GaN switch; and an on-chip magnetic inductor formed either on the GaN transistor chip or on the interposer chip. A method of forming a fully integrated DC-DC power converter is also provided.
