LTM4607 36VIN, 24VOUT High Efficiency Buck-Boost DC/DC µModule Regulator Description The LTM®4607 is a high efficiency switching mode buckboost power supply. Included in the package are the switching controller, power FETs,and support ponents. Operating over an input voltage range of 4.5V to 36V, the LTM4607 supports an output voltage range of 0.8V 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. The LTM4607 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics. Fault protection Features include overvoltage and foldback current protection. The DC/DC µModule® regulator is offered in a small thermally enhanced 15mm × 15mm × 2.8mm LGA package. The...
