LTM8031
Ultralow Noise EMC 36V, 1A
DC/DC µModule Regulator
DESCRIPTION
The LTM®8031 is an electromagnetic compatible (EMC)
36V, 1A DC/DC μModule® buck converter designed to
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 LTM8031 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 LTM8031 is packaged in a thermally enhanced, compact
(9mm × 15mm) and low profile (2.82mm) overmolded land
grid array (LGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8031 is
RoHS compliant.
