Continuous conduction mode SIMO device

Abstract:

A power converter is disclosed. The power converter includes a Single-Input-Multiple-Output (SIMO) device includes a first transistor connected to an input and a first end of an inductor, a second transistor connected to a second end of the inductor and a first output, and a third transistor connected to the second end of the inductor and a second output. The power converter also includes a controller connected to the SIMO device and is configured to maintain a minimum inductor current through the inductor between charging cycles and to cause the minimum inductor current to transition to a charging inductor current during a charging cycle. The charging inductor current is based on a difference between an output voltage signal and a target voltage signal.
