Description
General part information
LT3572 Series
The LT3572 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. APGOODpin indicates when the output of the boost converter is in regulation and the Piezo drivers are allowed to start switching.The LT3572 is available in a (4mm × 4mm) 20-pin QFN package.ApplicationsPiezo Motor Drive
