Product Overview
LTC3454 is a synchronous buck-boost DC/DC converter optimized for driving a single high power LED at currents upto 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. 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. It is widely used in application such as cell phone camera flash, cell phone torch lighting, digital cameras, PDAs, misc. Li-Ion LED drivers etc.
- Wide input voltage range is 2.7V to 5.5V
- Internal soft-start
- Open/shorted LED protection
- Oscillator frequency is 1MHz typical
- Zero shutdown current
- Overtemperature protection
- Upto 1A continuous output current
- Operating temperature is -40°C to 85°C
- Package style is 10-lead plastic DFN
