Description
LTM8003
40V
IN
, 3.5A Step-Down
μModule Regulator
Demonstration circuit 2416A features the
LTM
®
8003
, a
40V, 3.5A step-down μModule
®
Regulator. This demo
circuit is configured to deliver a 5.0V output from an input
voltage between 6.0V to 40V at a switching frequency
of 2MHz. The wide input range of the LTM8003 allows
a variety of input sources such as automotive batteries
and industrial supplies. Under light load conditions, the
available Burst Mode
®
operation supports high efficiency
with low output ripple.
