Abstract

Circuits, systems, and methods for dynamically controlling a power supply configuration in response to load requirements from a digital circuit are disclosed. To increase efficiency, the power supply is configurable to be switched into a lower capacity mode. To prevent the digital circuit from demanding capacity beyond the lower capacity mode of the power supply before the power supply can be switched into a higher capacity mode, at least one hardware interlock is employed. The hardware interlock(s) governs the power demand of the digital circuit from extending beyond the lower capacity mode of the power supply. If it is detected that the hardware interlock(s) limits power demand in the digital circuit beyond a power demand threshold, the power supply can be switched to the higher capacity mode. The hardware interlock(s) can then be disabled. In this manner, the power supply can dynamically provide increased capacity as demanded by the dynamic performance of the digital circuit.
