Synchronous Boost Converter  
FEATURES  
DESCRIPTION  
TheLTC®3459isalowcurrent,highefficiencysynchronous  
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 5.5V. The output is programmable via  
an external divider between 2.5V and 10V. Although the

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.
