Abstract: A power source delivers power from a main power source using switching by a normally on transistor. A driver switches on and off the normally on transistor under a control signal by a controller during regular operation. A housekeeping power supply delivers auxiliary power to the driver. The driver switches off the normally on transistor during irregular operation. Irregular operation occurs at least when the control signal is absent or no auxiliary power is available or during transients such a power up or down. Bridge block pairs thereof can be arranged to form a half bridge power switch, an H bridge switch, a three phase bridge switch, a multi-phase switch, a buck converter, a buck-boost converter, or a boost converter.

Abstract: An electronic apparatus includes a base substrate, the base substrate including an interconnect. The electronic apparatus further includes a first die including a first semiconductor device, the first semiconductor device being coupled to the interconnect, and further includes a second die including a second semiconductor device, the second semiconductor device being coupled to the interconnect. The first and second die are attached to the base substrate in opposite orientations.
