Abstract
A voltage converter comprises a step-down converter circuit (DCDC) with an inductive accumulator (LSW) and a first capacitive accumulator (CDC) and a charge pump circuit (CP) with at least one second capacitive accumulator (CFLY, CFLY,CFLY). The step-down converter circuit (DCDC) which can be fed a supply voltage (VBAT) on the input side is designed to charge the first capacitive accumulator (CDC) to a first intermediate voltage in switched mode. The charge pump circuit (CP) is designed to charge the at least one second capacitive accumulator (CFLY, CFLY,CFLY) to a second intermediate voltage using the supply voltage (VBAT) and to generate an output voltage from the first and second intermediate voltages.
