DESCRIPTION
Demonstration circuit 1195 features the LTM
step-down regulator preconfigured to deliver 3.3V at up
to 2A from a 5V to 36V input supply. The LTM8023 is a
step-down converter, so minimum amount of headroom
is required to keep the output in regulation. In addition,
the input voltage required to turn on is higher than that
required to run (see Minimum Input Voltage section in the
data sheet for detail). The optional Burst Mode
of LTM8023 supports high efficiency and low output ripple
at light load conditions.
