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

摘要

Power control systems and power control devices may include a power control chip having a power control module configured to generate a power stage control signal, and an external power stage having a timing control module. The timing control module may be configured to receive the power stage control signal and generate a timing control signal controlling at least one switch to regulate an output voltage of the external power stage. The power control device further includes an auto-configuration module configured to communicate with the external power stage and request auto-configuration information from the external power stage. A related method of auto-configuring a power control system includes 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.

1. A power control device, comprising:
a power control module configured to generate a power stage control signal indicating an offset between an output voltage and a reference voltage, and to externally transmit the power stage control signal to an external power stage having a timing control module that is physically separate from the power control module, the output voltage generated by the external power stage to power a load; and an auto-configuration module configured to communicate with the external power stage and request auto-configuration information from the external power stage.
