Product Overview

LT3572 is a highly integrated dual piezo motor driver capable of driving two piezo motors at upto 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. It is used in application such as piezo motor drive etc.
  • Input voltage range is 2.7V to 10V
  • Soft-start, separate enable for each piezo driver and boost converter
  • VIN quiescent current is 3.4mA typical at (VFB = 1.3V)
  • VIN shutdown current is 1μA maximum at (VSHDN = VSHDNA = VSHDNB = 0V)
  • Switching frequency is 500KHz typical
  • Synchronization frequency range is 575KHz to 2500KHz
  • Operating temperature is -40°C to 85°C
  • Package style is 20-lead plastic DFN
