Description

The LTC3114-1 is a versatile, wide operating voltage range synchronous monolithic 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 3?A in shutdown. Overtemperature protection, short-circuit protection and soft-start are integrated. The LTC3114-1 is offered in 16-lead 3mm ? 5mm ? 0.75mm DFN and 16 lead TSSOP (FE) packages.Applications 24V/28V Industrial Power Supply 12V Lead-Acid to 12V Regulator High Power LED Driver 12V/24V Solar Panel Battery Charging Systems Automotive Power Systems
