1. A voltage converter that receives at input a primary DC voltage that is variable over a wide voltage range and that supplies at output a regulated first secondary DC voltage and an unregulated second secondary DC voltage, comprising:
a buck converter with inductors coupled to two outputs,
a boost converter arranged upstream of the buck converter and able to boost the primary voltage when activated, and
a charge pump module arranged between the second secondary voltage and the first secondary voltage and able to balance charges when activated, the boost converter and the charge pump module being activated simultaneously.
