DC/DC µModule
The LTM
®
4600HV is a complete 10A, DC/DC step down
power supply with up to 28V input operation. Included
in the package are the switching controller, power FETs,
inductor, and all support components. Operating over
an input voltage range of 4.5V to 28V, the LTM4600HV
supports an output voltage range of 0.6V to 5V, set by a
single resistor. This high effi ciency design delivers 10A
continuous current (12A peak), needing no heat sinks or
airfl ow to meet power specifi cations. Only bulk input and
output capacitors are needed to fi nish the design.

The low profi le package (2.8mm) enables utilization of
unused space on the bottom of PC boards for high density
point of load regulation. High switching frequency and an
adaptive on-time current mode architecture enables a very
fast transient response to line and load changes without
sacrifi cing stability. Fault protection features include
integrated overvoltage and short circuit protection with
a defeatable shutdown timer. A built-in soft-start timer is
adjustable with a small capacitor.

The LTM4600HV is packaged in a thermally enhanced,
compact (15mm × 15mm) and low profi le (2.8mm) over-
molded Land Grid Array (LGA) package suitable for auto-
mated assembly by standard surface mount equipment.
The LTM4600HV is Pb-free and RoHS compliant.
