    Demo Board for LTM4601 Step-Down µModule Regulator

    Overview

    Demonstration circuit DC1041A-ADC1041A-A features the LTM4601EV, 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 ±5% from the nominal value is available via the margin control pins MARG0 and MARG1.

    Key Applications: Telecom and Networking Equipment, Servers, Industrial Equipment, Point of Load Regulation
