IPC: G06F1/26
Filed: 2018-08-21
Abstract: The present invention relates to systems, apparatuses, and methods for generating stable output voltage for one or more components by checking feedback information for an entire clock period. In various embodiments of the present invention, a power converter generates output voltage for one or more components. When load current, withdrawn by the one or more components, changes, inductor current of a low pass filter and monitored by a current sense amplifier also changes. The clock period is divided into a high phase and a low phase with one of the phases being a relatively short phase. During the relatively short phase, the current sense amplifier does not have sufficient time to measure feedback information. Instead of selecting voltage output of the current sense amplifier, control logic selects voltage output of a voltage generator, which emulates a voltage ramp with a slope of the inductor current during the relatively short phase.
