Abstract
An integrated circuit device for delivering power to a load includes a controller circuit, a cascade circuit, and a power delivery circuit. The controller circuit generates a plurality of control signals. The cascade circuit receives the control signals from the controller circuit and sequentially outputs the control signals onto a cascade bus. The power delivery circuit receives the control signals from the controller circuit and delivers an amount of current to the load, in response to one of the control signals.
Claims8
A system for delivering power to a load, the system comprising a plurality of power modules, wherein each of the plurality of power modules includes:
- a controller circuit to generate a plurality of control signals;
- a power delivery circuit to receive a selected control signal, wherein the power delivery circuit delivers an amount of current to the load based, at least in part, on the selected control signal;
- and
- a configuration circuit to (a) determine a total number of power modules in the system and generate information representative of the total number of power modules, and (b) determine a relative position in the system for a respective power module and generate information representative of the relative position.
