Abstract
A driver for a circuit with a capacitive load is configured for coupling to a voltage source which provides a DC input voltage, and is configured to generate an output voltage at an output. The driver includes a bidirectional synchronous power converter with a first switch, a second switch, and an inductive device connected to the first and/or second switch. A controller is configured to control the first switch and the second switch. The bidirectional synchronous power converter generates a switching voltage from the input voltage at a switching node and generates the output voltage having an analog voltage waveform with a peak amplitude of at least twice the input voltage.
