DESCRIPTION
The LTM
verter. Included in the package are the switching controller,
power switches, inductor and all support components.
Operating over an input voltage range of 3.6V to 36V, the
LTM8025 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
fi lter capacitors are needed to fi nish the design.
The low profi le package (4.32mm) enables utilization of
unused space on the bottom of PC boards for high density
point of load regulation.
The LTM8025 is packaged in a thermally enhanced, compact
(15mm × 9mm) and low profi le (4.32mm) over-molded
land grid array (LGA) package suitable for automated
assembly by standard surface mount equipment. The
LTM8025 is RoHS compliant.
