Abstract: A power control system comprises a plurality of POL regulators, at least one serial data bus operatively connecting the plurality of POL regulators, and a system controller connected to the serial data bus and adapted to send and receive digital data to and from the plurality of POL regulators. The serial data bus further comprises a first data bus carrying programming and control information between the system controller and the plurality of POL regulators. The serial data bus may also include a second data bus carrying fault management information between the system controller and the plurality of POL regulators. The power control may also include a front-end regulator providing an intermediate voltage to the plurality of POL regulators on an intermediate voltage bus.
