DRV8662: Drive sonar transducer 600w

Part Number: DRV8662
Hi, Is there a way to drive a 600W/1kW transducer with 50khz frequency and the DRV8662? If I configure the chip to output 200V differential and drive the primary side of a transformer and the secondary side boost the voltage for example 600v Would this circuit work?

    Hi Michael,

    The DRV8662 and other piezo haptic drivers are designed for haptic frequencies and have a max bandwidth of ~20kHz. You will need an ultrasonic driver for this application.
