Description
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 efficiency design delivers 10A
continuous current (12A peak), needing no heat sinks or
airflow to meet power specifications. Only bulk input and
output 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. High switching frequency and an
adaptive on-time current mode architecture enables a very
fast transient response to line and load changes without
sacrificing 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 compact (15mm ×
15mm) and low profile (2.82mm) over-molded Land Grid
Array (LGA) package suitable for automated assembly by
standard surface mount equipment. The LTM4600HV is
RoHS compliant.
