DESCRIPTION

Ultralow Noise

EMC Compliant 36V, 2A

DC/DC µModule

The LTM

36V, 2A DC/DC μModule

meet the radiated emissions requirements of EN55022.

Conducted emission requirements can be met by adding

standard filter components. Included in the package are the

switching controller, power switches, inductor, filters and

all support components. Operating over an input voltage

range of 3.6V to 36V, the LTM8032 supports an output

voltage range of 0.8V to 10V, and a switching frequency

range of 200kHz to 2.4MHz, each set by a single resistor.

Only the bulk input and output filter capacitors are needed

to finish the design. The low profile package (2.82mm)

enables utilization of unused space on the bottom of PC

boards for high density point of load regulation.

The LTM8032 is packaged in a thermally enhanced, compact

(9mm

×15mm)andlowprofile(2.82mm)overmoldedland

grid array (LGA) package suitable for automated assembly

by standard surface mount equipment. The LTM8032 is

RoHS compliant.
