DESCRIPTION
Demonstration circuit DC1041A-B features the
LTM
switch mode step-down converter. The input voltage
range is from 4.5V to 28V. The output voltage is jumper
selectable 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
