ZHCSHW2I June 2007 – September 2018 LM2735
PRODUCTION DATA.
The LM2735 can easily be converted into a SEPIC converter. A SEPIC converter has the ability to regulate an output voltage that is either larger or smaller in magnitude than the input voltage. Other converters have this ability as well (CUK and Buck-Boost), but usually create an output voltage that is opposite in polarity to the input voltage. This topology is a perfect fit for Lithium Ion battery applications where the input voltage for a single-cell Li-Ion battery will vary from 3 V to 4.5 V and the output voltage is somewhere in-between. Most of the analysis of the LM2735 Boost Converter is applicable to the LM2735 SEPIC Converter.
