Abstract: A system includes an input voltage supply and advanced current mode (ACM) converter device coupled to the input voltage supply. The ACM converter device (102) includes a pulse-skipping mode (PSM) transitions controller configured to switch between PSM and discontinuous conduction mode (DCM). The system also includes an output inductor coupled to a switch node of the ACM converter device. The system also includes an output capacitor with a first terminal coupled to the output inductor and a second terminal coupled to a ground node. The system also includes a voltage divider in parallel with the output capacitor, where the voltage divider is configured to provide a feedback voltage to the ACM converter device.
