DESCRIPTION
Demonstration circuit DC1041A-A features the
LTM
mode step-down converter. The input voltage range is
from 4.5V to 20V. The output voltage is jumper select-
able for popular voltages from 0.6V to 5V. The PLLIN
pin supports synchronizing the μModule
an external clock. The TRACK/SS pin allows the user to
program output ramp-up and ramp-down rates which
may coincidentally or ratiometrically track with another
supply’s output if desired. Output voltage margining of
