Abstract
In one implementation, a power semiconductor package includes a conductive carrier including a switch node segment and a power output segment. The power semiconductor package also includes an integrated output inductor stacked over the conductive carrier and configured to couple the switch node segment to the power output segment. The power semiconductor package further includes a power stage stacked over the integrated output inductor, the power stage including a pulse-width modulation (PWM) control and driver coupled to a control transistor and a sync transistor.
