The LTM4607IV#PBF is a high efficiency buck-boost DC/DC μModule (Power Module) Regulator with 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 high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The LTM4607 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics. Fault protection features include overvoltage and fold back current protection.
