The LTC3114EFE-1#PBF is a 40V 1A synchronous buck-boost DC/DC Converter with programmable average output current. The LTC3114-1's proprietary buck-boost PWM control circuitry delivers low noise operation across the entire operating voltage range. Current mode control ensures exceptional line and load transient responses. Synchronous, internal MOSFET switches and pin selectable Burst Mode? operation maintain high efficiency across the entire range of load current. Average output current is programmed with a standard resistor and provides the basis for wide input range, high efficiency charging systems or constant current, high efficiency LED drive. Regulator turn-on is programmable through the accurate RUN pin. Quiescent current is just 3μA in shutdown. Over-temperature protection, short-circuit protection and soft-start are integrated.
