LTC3115-1 Buck-Boost Converter

Linear Technology's 40 V, 2 A synchronous buck-boost DC/DC converter

Image of Linear Technology's LTC3115-1 Buck-Boost ConverterLinear Technology's LTC3115-1 is a synchronous buck-boost converter that delivers up to 2 A of continuous output current from a wide range of power sources, such as single-cell Li-Ion, 24 V/28 V industrial rails, and 40 V automotive inputs. The LTC3115-1's 2.7 V to 40 V input and output range provides a regulated output with inputs above, below or equal to the regulated output. The low noise buck-boost topology incorporated in the LTC3115-1 provides a continuous, jitter-free transition between buck and boost modes, making it ideal for RF and other noise-sensitive applications that must maintain a low-noise constant output voltage with a variable input power source.
