Patent ID: 8692535

Claim:
A method comprising: via a power supply controller operating a power supply in a discontinuous operational mode: monitoring current supplied by an inductor resource in the power supply to produce an output voltage to power a load; producing an adjustment value based on a magnitude of the current supplied by the inductor resource in the power supply to power the load; and utilizing the adjustment value to modify a trigger threshold voltage value and produce an adjusted trigger threshold voltage value at which the power supply controller initiates activation of a control switch in the power supply, activation of the control switch increasing current through the inductor resource to power the load; wherein monitoring the current supplied by the inductor resource includes: detecting the current supplied by the inductor resource based on a first portion of current and a second portion of current passing through the inductor resource during each of multiple discontinuous mode switching cycles, the first portion of current flowing through the inductor resource based on activation of the control switch in the power supply, the second portion of current flowing through the inductor resource based on activation of a synchronous switch in the power supply.
