Abstract: Systems, apparatuses and methods may provide for early pre-charge with respect to peak power events. Application performance may improve by pre-charging a supercap just prior to initiating a system wake up from a qualified system wake-source trigger. Additionally, the pre-charging of the supercap may be controlled by a time defined pre-charge period and may also be controlled by a predetermined threshold voltage.

Abstract: In some examples, an apparatus for reference voltage generation includes a plurality of reference voltage rails each with a corresponding reference voltage, a first controller, and a second controller. The first controller is to cycle through the plurality of reference voltage rails and maintain the reference voltages in a synchronous mode. The second controller is to detect an event and provide an indication to the first controller to update in an asynchronous mode one of the plurality of reference voltages in response to the event. The first controller is to update in an asynchronous mode the one of the plurality of reference voltages in response to the event.

Abstract: Embodiments described herein describe operating a master-slave controller. Operating the master-slave controller comprises, based on a determination that the first output voltage value is greater than the second output voltage value, calculating a first duty cycle value and an input voltage value and the second voltage regulator, calculating a second duty cycle value based on the first duty cycle value, and based on a determination that the second output voltage value is greater than or equal to the first output voltage value, calculating the second duty cycle value based on the second output voltage value and the input voltage value and calculating the first duty cycle value based on the second duty cycle value and configuring the first voltage regulator with the first duty cycle value and the second voltage regulator with the second duty cycle value.

Abstract: Embodiments described herein concern operating a peak-delivered-power (PDP) controller. Operating a PDP includes calculating the new power output value from the output voltage value and the output current value, determining whether the new power output value is greater than the previous power output value to determine whether the voltage regulator is outputting a maximum power output, based on a determination that the new power output value is greater than the previous power output value, providing an instruction to a duty generator to increase a duty cycle of the voltage regulator, based on a determination that the new power output value is not greater than the previous power output value, providing an instruction to the duty generator to decrease the duty cycle of the voltage regulator, and replacing the previous power output value with the new power output value.
