| 摘要 |
The invention relates to a voltage converter comprising a step-down converter circuit (DCDC) provided with an inductive accumulator (LSW), a first capacitive accumulator (CDC) and a charge pump circuit (CP) having at least one second capacitive accumulator (CFLY, CFLY1, CFLY2). Said step-down converter circuit (DCDC), which can receive on the input side a supply voltage (VBAT), is designed in such a manner that the first capacitive accumulator (CDC) is charged with a first intermediate voltage in the switched state. Said charge pump circuit (CP) is designed to charge the at least one second capacitive accumulator (CFLY, CFLY1, CFLY2) with a second intermediate voltage using the supply voltage (VBAT) and an output voltage is produced from the first and the second intermediate voltage. |
