The LT3572EUF#PBF is a highly integrated dual Piezo motor driver capable of driving two Piezo motors at up to 40V from a 5V supply. 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 drivers are allowed to start switching.
The LT3572EUF#PBF is available in a (4mm × 4mm) 20-pin QFN package.
