Abstract: A two-stage step-down converter includes a first stage and a second stage operatively connected to the first stage. The first stage is to step down an input voltage to an intermediate periodic signal and includes a primary side, a secondary side, and a plurality of transformers to electromagnetically couple the primary side and the secondary side to step down the input voltage to the intermediate periodic signal. The primary windings of the transformers are connected in series and the secondary windings are connected in parallel.

Abstract: A computing device including a motherboard. The motherboard is coupled to a memory socket, a power rail, and a regulator controller. The memory socket is able to couple to a circuit board that includes memory circuitry. The power rail provides a high-voltage power signal to power circuitry on the circuit board. The power rail provides the high-voltage power signal through the memory socket. The regulator controller provides a control signal to power circuitry on the circuit board. The control signal includes a pulse width modulation signal. An output voltage of the power circuitry on the circuit board may be controlled by the control signal.
