  • System and method for increasing power supply peak power capacity
    Patent number: 11726536
    Abstract: A method for increasing power supply voltage in an information handling system in a normal mode with a first peak voltage comprises, in response to receiving a request for a higher peak voltage, an embedded controller (EC) receiving information associated with the application including a request for power at a higher peak voltage, a housekeeping IC communicating a signal to a PWM IC to increase voltage supplied to the information handling system to the higher peak voltage, the PWM IC converting from the PSU to the higher peak voltage and starting a timer with a defined time period. If no additional requests for operating at the higher peak voltage are received before the time period expires, the PWM IC communicates a signal that power will stop being supplied at the higher peak voltage, and the information handling system returns to operating in the normal mode at the first peak voltage.
