DEMO MANUAL DC1194A
DESCRIPTION
LTM8020
36V, 200mA DC/DC
µModule Regulator
Demonstration circuit DC1194A features the LTM
®
8020, a
200mA DC/DC step-down μModule
®
regulator. The board
is preset to deliver a 3.3V output at up to 200mA load
current from an input voltage of up to 36V. The output
voltage may be modified by simply changing one resis-
tor. The LTM8020 data sheet must be read in conjunction
