DESCRIPTION

µModule Regulator

the package are the switching controller, power switches,

inductor and all support components. Operating over an

input voltage range of 3.4V to 40V, the LTM8065 supports

an output voltage range of 0.97V to 18V and a switching

frequency range of 200kHz to 3MHz, each set by a single

resistor. Only the input and output filter 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 LTM8065 is packaged in a thermally

enhanced,compactover-moldedballgridarray(BGA)pack-

age suitable for automated assembly by standard surface

mount equipment. The LTM8065 is RoHS compliant.
