LTC3454EDD#PBF - Linear Technology Function Overview

The LTC3454EDD#PBF is a 1A synchronous buck-boost high current LED Driver 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 (2.7 to 4.2V). LED current is programmable to one of four levels, including shutdown with dual external resistors and dual enable inputs. In shutdown no supply current is drawn. A high constant operating frequency of 1MHz allows the use of small external components.
High efficiency (>90% typical in torch mode, >80% in flash mode)
3.5% LED current programming accuracy
Internal soft-start
Open/shorted LED protection
Zero shutdown current
Over-temperature protection
