DESCRIPTION
The
LTM

8003
is a 40V
IN
, 6A peak, 3.5A continuous
step-down Silent Switcher µModule

(power module)
regulator. The Silent Switcher architecture minimizes EMI
while delivering high efficiency at frequencies up to 3MHz.
Included in the package are the switching controller, power
switches, inductor, and all support components. Operating
over an input voltage range of 3.4V to 40V, the LTM8003
supports an output voltage range of 0.97V to 18V and a
switching frequency range of 200kHz to 3MHz, each set by
a single resistor. Only the input and output filter capacitors
are needed to finish the design.
The low profile package enables utilization of unused
space on the bottom of PC boards for high density point of
load regulation. The LTM8003 is packaged in a thermally
enhanced, compact over-molded ball grid array (BGA) pack-
age suitable for automated assembly by standard surface
mount equipment. The LTM8003 is RoHS compliant.
