Apparatuses and system and method for auto-configuration of a power control system

A power control device, comprising:

• a timing control module configured to receive a power stage control signal from a power control chip having a power stage control module that is physically separate from the timing control module, and to generate a timing control signal that controls a duty cycle for a voltage converter responsive to the power stage control signal;
• and
• an auto-configuration module configured to receive an auto-configuration request from the power control chip and respond to the request.

A power control system, comprising:

• a power control chip having a power control module configured to generate a power stage control signal;
• and
• at least one external power stage configured to receive the power stage control signal and provide a regulated current to a load, wherein each of the power control chip and the at least one external power stage include auto-configuration modules configured to communicate auto-configuration information therebetween.

A method of auto-configuring a power control system, the method comprising:

• communicating auto-configuration information between at least one external power stage of a power control system and a power control chip;
• and
• configuring a setting of the at least one external power stage of the power control system based on the auto-configuration information.
