Abstract

A power control system comprises at least one point-of-load (POL) regulator adapted to provide an output voltage to a corresponding load and a system controller connected to the POL regulator via a data bus and adapted to send a first data message in a first format to the POL regulator via the data bus. A bus translator is interposed along the data bus between the POL regulator and the system controller. The bus translator converts the first data message from the first format to a second format that is compatible with the POL regulator. The bus translator is adapted for bidirectional operation to convert a second data message communicated from the POL regulator in the second format to the first format. The bus translator may further include a phase-locked loop circuit adapted to synchronize operation of the bus translator to a detected data rate of the data bus.
