supply. Included in the package are the switching control-
ler, power FETs, inductor, and all support components.
Operating over an input voltage range of 4.5V to 20V, the
LTM4600 supports an output voltage range of 0.6V to 5V,
set by a single resistor. This high ef?ciency design delivers
10A continuous current (14A peak), needing no heat sinks
or air?ow to meet power speci?cations. Only bulk input
and output capacitors are needed to ?nish the design.
The low pro?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
sacri?cing stability. Fault protection features include
integrated overvoltage and short circuit protection with
a defeatable shutdown timer. A built-in soft-start timer is

TYPICAL APPLICATION
10A μModule Power Supply with 4.5V to 20V Input
adjustable with a small capacitor.
The LTM4600 is packaged in a thermally enhanced, compact
(15mm × 15mm) and low pro?le (2.8mm) over-molded
Land Grid Array (LGA) package suitable for automated
assembly by standard surface mount equipment. The
LTM4600 is Pb-free and RoHS compliant.
