Tiny, Low Profile 6.25mm × 9mm × 3.32mm RoHS

Compliant BGA Package

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 LTM8053 supports

an output voltage range of 0.97V to 15V 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 LTM8053 is packaged in a thermally

enhanced,compactover-moldedballgridarray(BGA)pack-

age suitable for automated assembly by standard surface

mount equipment. The LTM8053 is RoHS compliant.
