LTM4605EV#PBF

LTM4605 is a high efficiency switching mode buckboost power supply. Included in the package are the switching controller, power FETs, and support components. Operating over an input voltage range of 4.5V to 20V, it supports an output voltage range of 0.8V to 16V, set by a resistor. This high efficiency design delivers upto 5A continuous current in boost mode (12A 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. It can be frequency synchronized with an external clock to reduce undesirable frequency harmonics. It is used in application such as telecom, servers and networking equipment, industrial and automotive equipment, high power battery-operated devices etc.
