DESCRIPTION
Demonstration circuit 1386 features the LTM
2A EN55022 Class B certifi ed step-down converter. This
μModule
®
regulator is confi gured to deliver a 3.3V output
from an input voltage between 5.5V to 36V at a switching
frequency of 600kHz. The wide input range of the LTM8032
allows a variety of input sources. Under light load condi-
tions, the available Burst Mode
effi ciency with low output ripple.
