LTC3454EDD#PBF Description

The LTC3454EDD#PBF is a synchronous buck-boost DC/DC converter optimized for driving a single high-power LED at currents up to 1A from a single-cell Li-Ion battery input. The regulator operates in either synchronous buck, synchronous boost, or buck-boost mode depending on input voltage and LED forward voltage. PLED/PIN efficiency greater than 90% can be achieved over the entire usable range of a Li-Ion battery (2.7V to 4.2V).
