Abstract
Regulating voltages. At least some of the illustrative embodiments are systems including a switching circuit configured to produce an intermediate voltage signal from an input voltage signal, and a first voltage regulator coupled the switching circuit and configured to produce a first regulated voltage signal from the intermediate voltage signal. The switching circuit is configured to create the intermediate voltage signal based on a switching signal having a duty cycle, and wherein the duty cycle of the switching signal is open-loop with respect the intermediate voltage signal and the first regulated voltage signal.
