in the package are the switching controller, power FETs,
inductor, and all support components. Operating over
input voltage ranges of 4.5V to 26.5V, the LTM4619 supports two outputs with voltage ranges of 0.8V to 5V, each
set by a single external resistor. Its high efficiency design
delivers 4A continuous current (5A peak) for each output. n High switching frequency and a current mode architecture
enable a very fast transient response to line and load
changes without sacrificing stability. The two outputs …
