Multi-regulator power supply chip with common control bus

An electrical circuit comprising:

• a first integrated circuit that receives a first power signal and transmits first power control information that is based, at least in part, on a characteristic of the first power signal;
• a second integrated circuit that receives a second power signal and transmits second power control information that is based, at least in part, on a characteristic of the second power signal;
• and
• a power supply integrated circuit comprising:
• a first power regulator module that controls at least one characteristic of the first power signal;
• a second power regulator module that controls at least one characteristic of the second power signal;
• and
• a communication interface module that receives the first power control information from the first integrated circuit over a data bus, and receives the second power control information from the second integrated circuit over the data bus.

In a power supply integrated circuit comprising a first power regulator and a second power regulator, a method for controlling electrical power, the method comprising:

• receiving first power control information over a data bus;
• receiving second power control information over the data bus;
• controlling at least one characteristic of a first power signal by controlling operation of the first power regulator based, at least in part, on the first power control information;
• and
• controlling at least one characteristic of a second power signal by controlling operation of the second power regulator based, at least in part, on the second power control information.

In a power supply integrated circuit comprising a plurality of power regulators, a method for controlling electrical power, the method comprising:

• receiving power control information over a data bus;
• determining which of the plurality of power regulators corresponds to the received power control information;
• determining a regulator control signal based, at least in part, on the received power control information;
• and
• communicating the determined regulator control signal to the determined power regulator(s).
