Demonstration circuit DC1041A-A features the
LTM®4601EV, a 12A high efficiency, high density switch
mode step-down converter. The input voltage range is
from 4.5V to 20V. The output voltage is jumper selectable for popular voltages from 0.6V to 5V. The PLLIN
pin supports synchronizing the μModule® regulator to
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
L, LT, LTC, LTM, μModule, Linear Technology and the Linear logo are registered trademarks of
Linear Technology Corporation. All other trademarks are the property of their respective owners.
