The LTM4607EV#PBF is a high efficiency buck-boost DC/DC Module Regulator. Included in the package are the switching controller, power FETs and support components. Operating over an input voltage range of 4.5 to 36V, the LTM4607 supports an output voltage range of 0.8 to 24V, set by a resistor. This high efficiency design delivers up to 5A continuous current in boost mode (10A in buck mode). Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design. The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. This can be frequency synchronized with an external clock to reduce undesirable frequency harmonics.
