Low Noise Silent Switcher® Architecture
step-down Silent Switcher µModule® (power module)
regulator. Included in the package are the switching con-
troller, power switches, inductor, and all support compo-
nents. Operating over an input voltage range of 3.4V to
60V, the LTM8073 supports an output voltage range of
0.8V 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 LTM8073 is packaged in a thermally
enhanced, compact over-molded ball grid array (BGA)
package suitable for automated assembly by standard sur-
face mount equipment. The LTM8073 is RoHS compliant.
