LTC3459ES6#TRMPBF

LTC3459 is a low current, high efficiency synchronous boost converter intended for low power, size constrained portable applications. It 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 part is primarily intended for boost applications, VOUT will maintain regulation below VIN (at reduced efficiency). It 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. It is used in application such as general purpose micropower boost, digital cameras, PDAs, LCD bias, small OLED displays, supercap charging etc.
