DescripTion
EN55022B Compliant 36V,
2A DC/DC µModule
Regulator
The
is an electromagnetic compatible (EMC)
36V, 2A DC/DC step-down µModule
®
regulator 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 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 enables uti-
lization of unused space on the bottom of PC boards for
high density point of load regulation.
The LTM8032 is packaged in a thermally enhanced, com-
The LTM8032 is packaged in a thermally enhanced, com-
pact and low profile overmolded land grid array (LGA) and
ball grid array (BGA) packages suitable for automated
assembly by standard surface mount equipment. The
LTM8032 is available with SnPb (BGA) or RoHS compli-
ant terminal finish.
