Peak-delivered-power circuit for a voltage regulator
First Claim
1. A peak-delivered-power (PDP) controller, comprising:
- memory to store a previous power output value and a new power output value, wherein the previous power output value and the new power output value correspond with power after a buck-boost power stage of a voltage regulator at a first time and a second time respectively;
measurement circuitry to measure an output voltage value and an output current value after the buck-boost power stage of the voltage regulator; and
control circuitry to;
calculate the new power output value after the buck-boost power stage from the output voltage value and the output current value;
determine whether the new power output value after the buck-boost power stage is greater than the previous power output value after the buck-boost power stage to determine whether the voltage regulator is outputting a maximum power output;
based on a determination that the new power output value after the buck-boost power stage is greater than the previous power output value after the buck-boost power stage, provide 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 after the buck-boost power stage is not greater than the previous power output value after the buck-boost power stage, provide an instruction to the duty generator to decrease the duty cycle of the voltage regulator; and
replace the previous power output value with the new power output 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.
