DESCRIPTION
LTM8031:
Ultralow Noise, EMC 36V, 1A
DC/DC µModule
®
Regulator
Demonstration circuit DC1597A features the LTM
®
8031, a
step-down converter certified to meet the EN55022 radi-
ated emissions standard. The LTM8031 is configured to
deliver a 3.3V output from a 5V to 36V input with a 750kHz
operating frequency. The wide input range supports a
variety of input sources, such as automotive batteries,
wall adaptors and industrial supplies. Under light load
conditions, the LTM8031 enters Burst Mode
