Product Overview

The LT3470ETS8#TRMPBF is a micropower step-down DC/DC Converter that integrates a 300mA power switch, catch diode and boost diode into low profile 3mm x 2mm DD. It combines burst mode and continuous operation to allow the use of tiny inductor and capacitors while providing a low ripple output to loads of up to 200mA. With its wide input range of 4V to 40V, it can regulate a wide variety of power sources, from 2-cell Li-ion batteries to unregulated wall transformers and lead-acid batteries. Quiescent current in regulation is just 26µA in a typical application while a zero current shutdown mode disconnects the load from the input source, simplifying power management in battery-powered systems. Fast current limiting and hysteretic control protects this converter and external components against shorted outputs, even at 40V input.
  • 26µA at 12VIN to 3.3VOUT Low quiescent current
  • Integrated boost and catch diodes
  • <10mV Low output ripple
  • <1µA in Shutdown mode
  • 200mA Output current
  • Hysteretic mode control
