ABSTRACT:
Systems and techniques for efficient power regulators with improved reliability. A power regulator may include a first driver including a first switch and a second switch, where a power dissipation of the first switch is less than a power dissipation of the second switch. The power regulator may include a second driver. The first and second switches may be implemented as transistors, which may have different on-state breakdown voltages and/or on-state drain source resistances.
