DESCRIPTION

36V, 1.5A 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.

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.
