LTC3531EDD#PBF

LTC3531 is a synchronous buck-boost DC/DC converter. It 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 converters operate in Burst Mode, minimizing solution footprint and component count as well as providing high conversion efficiency over a wide range of load currents. It is widely used in application such as handheld instruments, MP3 players, handheld computers, PDA/GPS etc.
