LTC3118 Datasheet 2a Buck-boost DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

General Description

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 flexibility and voltage margin for a wide variety of applications and power sources.
