ABSTRACT:
A controller circuit in a power supply system is configured to simultaneously control both a voltage regulator circuit and a dynamic power supply circuit. The controller circuit monitors voltage produced by the voltage regulator circuit. The voltage regulator circuit conveys power from a voltage source to a dynamic load such as a microprocessor, whose power consumption can change rapidly change during operation. Depending on a state (e.g., current value, trend, etc.) of the monitored voltage applied to the load by the voltage regulator circuit, the controller circuit can initiate activation of the dynamic power supply circuit in parallel with the voltage regulator circuit to selectively supply additional power to the load. Supplying additional power to the dynamic load during heavy load conditions prevents the regulated voltage supplied to the load from falling below a threshold value.
