DESCRIPTION

Silent Switcher µModule

Regulator

Includedinthepackagearetheswitchingcontroller,power

switches,inductor,andallsupportcomponents.Operating

over an input voltage range of 3.4V to 40V, the LTM8003

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 LTM8003 is packaged in a thermally

enhanced,compactover-moldedballgridarray(BGA)pack-

age suitable for automated assembly by standard surface

mount equipment. The LTM8003 is RoHS compliant.
