A power system includes a switching circuit, a resonant tank, a feedback circuit, and controller circuitry. The switching circuit including a first switch and a second switch provides a first AC signal. The resonant tank coupled to the switching circuit receives the first AC signal and generating a second AC signal for powering a load. The feedback circuit coupled to the load monitors an electrical condition of the load and provides a feedback signal. The controller circuitry coupled to the converter controls the switching circuit according to the feedback signal so as to control the power to the load. The controller circuitry is integrated in a first die. The first switch is integrated in a second die, and the second switch is integrated in a third die. The first die, said second die and said third die are mounted on and electrically interconnected to a platform compatible with through-hole technology. The platform and the resonant tank are further assembled on a printed circuit board.
