Abstract
A single die driver integrated circuit is coupled to an input portion having a single inductor receiving a low voltage source and configured to drive a capacitive load with an output voltage. The driver includes a bidirectional synchronous power converter stage configured to generate a switching voltage from the input portion at a switching node and to generate a high voltage waveform from the low-voltage source. An embedded controller is configured to control a switch of the power converter stage.
