Abstract

In one implementation, an integrated power stage includes a common die situated over a load stage, the common die includes a driver stage and power switches. The power switches include a control transistor and a sync transistor. A drain of the control transistor receives an input voltage of the common die on one side (e.g., on a top surface) of the common die. A source of the control transistor is coupled to a drain of the sync transistor and provides an output voltage of the common die on an opposite side (e.g., on a bottom surface) of the common die. An interposer may be included under the power stage and includes an output inductor and optionally an output capacitor coupled to the output voltage of the common die on the opposite side of the common die.
