Methods and apparatuses for controlling an apparatus comprising a controller integrated in a first slave device. In an example, the controller can detect a sensed current of the first slave device. The controller can receive a voltage signal associated with a second slave device connected to the first slave device. The controller can generate a correction current based on the sensed current of the first slave device and the voltage signal. The controller can modulate a pulse width modulation (PWM) signal received by the first slave device using the correction current. The controller can control a power converter using the modulated PWM signal.

Integrated current sharing schemes for multiplying power stages support of a multiphase controller

The present embodiments relate to methods and apparatuses for providing fault protection in a power controller such as a voltage regulator, and particularly protection against reverse over current fault conditions. Some embodiments are capable of distinguishing between different types of reverse over current conditions, such as a high-side short or a normal over voltage condition. In these and other embodiments, fault protection is performed in favor of a load connected to the voltage regulator, rather than components of the voltage regulator itself.
