DC/DC µModule® (power module) regulator. Included in
the package are the switching controller, power FETs, inductor and all supporting components. Operating over an
input voltage range of 4.7V to 15V, the LTM4645 supports
an output voltage range of 0.6V to 1.8V, set by a single
external resistor. Only a few input and output capacitors
are needed. n Its high efficiency design delivers about 86% efficiency
from 12V input to 1.0V output with 25A continuous load
current. High switching frequency and a current-mode
architecture enable a very fast transient response to line …
