LTC3114IFE-1#PBF Description
The LTC3114IFE-1#PBF is a versatile, wide operating voltage range synchronous monolithic buck-boost DC/DC converter with a programmable average output
current. The LTC3114IFE-1#PBF’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 load current range. 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.
