1 / 34 page  LTC3114-1 1 Rev. D For more information www.analog.com Document Feedback TYPICAL APPLICATION FEATURES DESCRIPTION 40V, 1A Synchronous Buck-Boost DC/DC Converter with Programmable Output Current The LTC®3114-1 is a versatile, wide operating voltage range synchronous monolithic buck-boost DC/DC con- verter with programmable average output current. The LTC3114-1’s proprietary buck-boost PWM control cir- cuitry 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 select- able 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 accu- rate RUN pin. Quiescent current is just 3µA 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.
