LTC3118 - Linear Technology

LTC3118 2A Buck-Boost DC/DC Converter

The LTC®3118 is a dual-input, wide voltage range synchronous buck-boost DC/DC converter with an intelligent, integrated, low loss PowerPath control. The unique power switch architecture provides efficient operation from either input source to a programmable output voltage above, below or equal to the input. Voltage capability of up to 18V provides flexibilit.
