摘要： According to example configurations as described herein, a power supply system includes a unique circuit including an analog summer circuit, an analog-to-digital converter, and a digital controller. An output voltage feedback control loop of the power supply system feeds back the output voltage to the analog summer circuit. The analog summer circuit generates an analog error voltage signal based on: i) the output voltage received from the output voltage feedback loop, ii) an analog reference voltage signal, and iii) an analog reference voltage adjustment signal. The analog reference voltage adjustment signal varies depending on a magnitude of current provided by the output voltage to the dynamic load. Accordingly, the analog summer circuit can be configured to support adaptive voltage positioning. The analog-to-digital converter converts the analog error voltage signal into a digital error voltage signal. A controller generates output voltage control signal(s) based on the digital error voltage signal.

摘要： In an example configuration, a power supply manager receives an output current value representing an amount of output current supplied by one or more power converter phases to a load. The power supply manager also receives a duty cycle value representing a duty cycle for controlling operation of the at least one power converter phase. The power supply manager produces an estimate of input current supplied to the power supply circuit based at least in part on multiplying the output current value by the duty cycle value. Contrary to conventional methods such as physically measuring an input current using complex measuring circuitry, embodiments herein include utilizing parameter information such as output current information and duty cycle information to deduce an amount of input current.

摘要： According to one configuration, a multi-phase power supply adjusts a number of active phases based at least in part on a peak current supplied to a dynamic load. For example, a controller associated with the multi-phase power supply can monitor or receive a value indicative of a peak magnitude of current delivered by the multi-phase power supply to a dynamic load. The controller initiates comparison of the value to threshold information. Based at least in part on the comparison, the controller adjusts how many phases of the multi-phase power supply are activated to deliver the current delivered to the dynamic load. Thus, one embodiment herein is directed to controlling a multi-phase power supply based at least in part on a measured parameter such as peak current magnitude.

摘要： A control circuit generates an output based on the first signal and the second signal by encoding the output to be a multi-state signal having at least three states. A magnitude of the multi-state signal generated by the controller varies depending on binary states of the first signal and the second signal. The controller utilizes the output (i.e., the multi-state signal) to control a switching circuit. A driver circuit receives the output generated by the control circuit. In one embodiment, the multi-state signal has more than two different logic states. The driver decodes the multi-state signal for generating signals to control switches in the switching circuit. One signal generated by the driver circuit is a pulse width modulation signal; another signal generated by the driver circuit is an enable/disable signal.
