Product Summary

The LTC3531EDDTR#PBF is a Buck-Boost Synchronous DC/DC Converter. The LTC3531EDDTR#PBF is synchronous buck-boost DC/DC converters that operate from input voltages above, below or equal to the output voltage. The topology incorporated in the ICs provides a continuous transfer through all operating modes, making the product ideal for single cell Li-Ion and multicell alkaline or nickel applications. The LTC3531EDDTR#PBF operates in Burst Mode, minimizing solution footprint and component count as well as providing high conversion effi ciency over a wide range of load currents.The applications of the LTC3531EDDTR#PBF include Handheld Instruments, MP3 Players, Handheld computers and PDA/GPS.
