LTC3114HFE-1#PBF

LINEAR TECHNOLOGY  LTC3114HFE-1#PBF  直流-直流开关升压, 降压稳压器, 可调, 2.2V-40V输入, 2.7V-40V输出, 1A输出, TSSOP-16

The is a versatile synchronous monolithic buck-boost DC-to-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.
