DESCRIPTION
Ultralow Noise EMC 36V
IN
,
3A DC/DC µModule
Regulator
The
is an electromagnetic compatible (EMC)
36V, 3A 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 LTM8033 supports an output
voltage range of 0.8V to 24V, 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 LTM8033 is packaged in a compact (11.25mm
The LTM8033 is packaged in a compact (11.25mm
× 15mm
× 4.32mm) overmolded land grid array (LGA) and ball grid
array (BGA) package suitable for automated assembly by
standard surface mount equipment. The LTM8033 is avail-
able with SnPb (BGA) or RoHS compliant terminal finish.
