Abstract: 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 at least one power stage having a timing control module that is physically separate from the power 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 at least one power stage. A related method may include generating power stage control information indicating an offset between an output voltage and a desired regulated output voltage, transmitting the power stage control information between modules that are physically separate, and timing signals for controlling a switching converter to regulate the output voltage. A related method of auto-configuring a power control system is also disclosed.

Abstract: In one general aspect, a power supply circuit can include a power stage configured to be coupled to a power source and configured to deliver an output voltage to a load circuit, and can include a comparator coupled to the power stage and configured to receive a reference voltage. The power supply circuit can also include a hysteresis control circuit configured to receive at least one of a feedback voltage or a reference voltage and configured to change a hysteresis of the comparator in response to the at least one of the feedback voltage or the reference voltage during a soft-start of the power supply circuit.

Abstract: In one general aspect, an apparatus can include a controller, and a power stage coupled to the controller and configured to be coupled to a power source. The power stage is configured to deliver an output voltage to a load module in response to the controller. The apparatus also includes a reference voltage circuit coupled to the controller and configured to be grounded to a first ground voltage different from a second ground voltage associated with the load module.
