In response to a determination that the compensated current is greater than a demand current generated using a voltage level of the power supply node and a reference voltage, the first phase unit may halt the charge cycle.Fabio GozziniJay B. FletcherShawn SearlesSanjay Pant...
The small-signal model of a peak current-mode buck converter [1] [2] will be introduced in this section. The Buck PWM Switch Model, proposed by V. Vorperian [1] and the small-signal model for peak current-mode control, by Raymond B. Ridley [2] are displayed in Figure 3. The equat...
Current-mode control is an alternative method for regulating output voltage in a DC/DC converter. The goal is to achieve a constant output voltage from a switchingDC/DC converterby measuring the current passing through the inductor. This should not be confused with current regulation, or constant...

An example buck converter in continuous-conduction mode is considered. A comprehensive characterization is presented for the proposed scheme. An overall dc and small-signal analysis of the inner current loop is performed. The current average current-mode control methods suffer from switching instability...
