LTC3454EDD - 1A Synchronous Buck-Boost High Current LED DriverThe LTC®3454 isA synchronous buck-boost DC/DC converter optimized for drivingA single high power LED at currents up to 1A fromA 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 ofA Li-Ion battery (2.7V to 4.2V).
