DESCRIPTION
The LTM®8063 is a 40VIN, 2A continuous, 2.5A peak, step-
down µModule® (power module) regulator. Included in
the package are the switching controller, power switches,
inductor, and all support components. Operating over an
input voltage range of 3.2V to 40V, the LTM8063 supports
an output voltage range of 0.8V to 15V and a switching
frequency range of 200kHz to 2.2MHz, 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 LTM8063 is packaged in a thermally en-
hanced, compact over-molded ball grid array (BGA) package
suitable for automated assembly by standard surface mount
equipment. The LTM8063 is RoHS compliant.
