1. Description

The LTM4607EV#PBF is a high efficiency switching mode buckboost power supply. Included in the package are the switchingcontroller, powerFETs, andsupportcomponents. Operating over an input voltage range of 4.5V to 36V, the LTM4607EV#PBF 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 lowprofilepackage enablesutilizationofunusedspace 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 LTM4607EV#PBF 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 LTM4607EV#PBF is Pb-free and RoHS compliant.
