DC/DC µModule
DESCRIPTION
The LTM®8032 is an electromagnetic compatible (EMC)
36V, 2A DC/DC μModule® buck converter designed to
meet the radiated emissions requirements of EN55022.
Conducted emission requirements can be met by adding
standard ï¬lter components. Included in the package are the
switching controller, power switches, inductor, ï¬lters 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 ï¬lter capacitors are needed
to ï¬nish the design. The low proï¬le 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 à 15mm) and low proï¬le (2.82mm) overmolded land
grid array (LGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8032 is
RoHS compliant.
