Abstract
A voltage converter device includes a voltage regulator having a supply terminal for receiving a supply voltage and an output terminal for providing a regulated voltage. A voltage multiplier is for receiving the regulated voltage and providing a boosted voltage higher in absolute value than the regulated voltage. The voltage multiplier includes circuitry for providing a clock signal that switches periodically between the regulated voltage and a reference voltage, and a sequence of capacitive stages that alternately accumulate and transfer electric charge according to the clock signal for generating the boosted voltage from the regulated voltage. The voltage regulator includes a power transistor and a regulation transistor each having a first conduction terminal, a second conduction terminal and a control terminal.
