Product Overview

The LTC3459ES6#TRMPBF is a 10V micropower synchronous Boost Converter intended for low power, size constrained portable applications. The LTC3459 can be powered from a single lithium ion battery, a 2- to 3-cell stack of Alkaline or Nickel batteries or any low impedance voltage source between 1.5V and 5.5. The output is programmable via an external divider between 2.5 and 10V. Although the part is primarily intended for boost applications, VOUT will maintain regulation below VIN (at reduced efficiency). The LTC3459 offers Burst Mode® operation with a fixed peak current, providing high conversion efficiency over a wide range of load currents. During start-up, inductor current is controlled preventing the inrush surge current found in many boost converters. In shutdown the output is disconnected from the input and quiescent current is reduced to <1µA.
  • Small solution size
  • >85% Efficiency over wide load range
  • Internal synchronous rectifier
  • 5V at 30mA from 3.3V input
  • 3.3V at 20mA from 2 AA cell input
  • Programmable output voltages up to 10V
  • Burst Mode® operation
  • Inrush current limiting
  • Output disconnect in shutdown
  • Ultralow quiescent (10µA) and shutdown (<1µA) currents
