    Demo Board for LTM4603 Synchronizable 20V, 6A Step-Down µModule Regulator

    Overview

    Demonstration circuit DC1083A-ADC1083A-A features the LTM4603, the high efficiency, high density step-down μModule regulator. The input voltage range is from 4.5V to 20V. The output voltage is jumper programmable from 0.6V to 5V. The rated load current is 6A, while derating is necessary for certain VIN, VOUT, and thermal conditions.

    Applying an external clock signal to the PLLIN pin forces the μModule regulator to operate at the same frequency. The output ramp-up and ramp-down may be programmed through the TRACK/SS pin. Margining function is provided for the user who wants to stress their system by varying supply voltages during testing.

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