The LT3572EUF#PBF is a highly integrated dual full-bridge Piezo Motor Driver with 900mA boost converter. Each Piezo driver can be independently turned ON or OFF along with the boost converter. The boost regulator has a soft-start capability that limits the inrush current at start-up. The boost regulator switching frequency is set by an external resistor or the frequency can be synchronized by an external clock. A PGOOD pin indicates when the output of the boost converter is in regulation and the Piezo driver is allowed to start switching.
