Abstract: Operational mode changes in a system-on-a-chip (SoC) integrated circuit in a complex device such as a mobile phone cause spikes in current demand which can cause voltage droops that disrupt operation of the SoC. A hybrid parallel power supply connects a switching-mode power supply and a low-dropout voltage regulator in parallel to provide high efficiency and fast response times. Integration of the voltage regulator on the SoC reduces parasitic impedance be between the voltage regulator and the load to aid in reducing voltage droops. The switching-mode power supply and the low-dropout voltage regulator can regulate their outputs to slightly difference voltage levels. This can allow the switching-mode power supply to supply most of the SoC's current demands.

Abstract: A method for temperature mitigation includes receiving a signal from a temperature sensor that is disposed within a computing device. A processor chip within the computing device produces heat. The signal from the temperature sensor is converted to temperature data. The method further includes processing the temperature data to generate an estimate of a temperature of an external surface of the device. The processing includes applying a low pass filter to the temperature data, applying an amplitude attenuation to the temperature data, and applying a delay to the temperature data. The method further includes reducing an operating parameter of the processor chip, such as operating frequency, in response to the estimated temperature of the external surface of the device.

Abstract: An apparatus and method are disclosed for providing voltage control at a load of a buck converter. The buck converter is in a feedback loop so that a reference voltage determines a pulse width modulated (PWM) signal that is fed to the buck converter, and an output voltage of the buck converter is fed back to a PWM control circuit to maintain a value of the output voltage. The load at the buck converter provides event counters to a transient load current prediction circuit, which uses a curve fitting algorithm or other adaptive control algorithm to predict a change in current at the load. The transient load current prediction circuit then manipulates the reference voltage in accordance with the predicted change in current at the load.
