Abstract
A power supply circuit can be configured to include a first circuit and a second circuit. Each circuit can be substantially identical to each other but provide different functionality depending on how they are configured. For example, each of the first circuit and second circuit can be chips having substantially the same pin layout and internal circuitry. However, the functionality provided by the circuits varies depending on whether a respective circuit is configured as a master or slave. The first circuit is configured as the master and generates multiple phase control signals. The first circuit uses a portion of the multiple phase control signals to control a first set of phases. The first circuit transmits a second portion of the multiple phase control signals to the second circuit configured as a slave. The second circuit is configured to receive and use the second portion of control signals to control a second set of phases.
