LTM8083
36V, 1.5A Buck-Boost
µModule Regulator
FEATURES
DESCRIPTION
The LTM®8083 is a 36VIN, Buck-Boost µModule® Regulator.
Included in the package are the switching controller, power
switches, inductor, and support components. All that is
needed to complete the design is resistors for setting the
output voltage and operating frequency, and input and
output capacitors. Operating over an input voltage range
from 3V to 36V, the LTM8083 can regulate output volt-
ages between 1V and 36V with seamless low-noise tran-
sitions between operation regions, as well as controlling
both input and output average currents through external
sense resistors.

6.25mm × 6.25mm × 2.22mm BGA Package
The low profile package enables utilization of unused
space on the bottom of PC boards for high density point
of load regulation. The LTM8083 is packaged in ther-
mally enhanced, compact over-molded Ball Grid Array
(BGA) packages suitable for automated assembly by
standard surface mount equipment. The LTM8083 is
RoHS compliant.
