Abstract

A switchable power converter includes a switchable power stage comprising an inductor and a capacitor for generating an output voltage according to a switching signal and an input voltage via a switching element comprising a high-side switch and a low-side switch driven by a driver according to the switching signal generated either in a digital control path or a constant-on-time control path. A multi-mode controller is configured to toggle between a light load mode in which the constant-on-time control path is activated and a high load mode in which the digital control path is activated. The multi-mode controller is further configured to generate a control signal for turning on the high-side switch for an additional time when transitioning from the light load mode to the high load mode.
