LTC3525-3 - 400mA Micropower Synchronous Step-Up DC/DC Converter

Description

The LTC®3525-3/LTC3525-3.3/LTC3525-5 are high efficiency synchronous step-up DC/DC converters with output disconnect that can start up with an input as low as 0.85V.

They offer a compact, high efficiency alternative to charge pumps in single cell or dual cell alkaline or Li-Ion applications.
