    Product Details

    Demonstration circuit 1118A-A features two independent LTM4601EV high efficiency, high density switch mode step-down power modules. The input voltage range is from 5V to 20V. The output voltages are 3.3V and 2.5V; refer to step down ratio curve in the LTM4601 datasheet. The rated load currents are 10A for the 3.3V output and 12A for the 2.5V output, while derating is necessary for certain VIN and thermal conditions. The output of U2 is set to coincidentally track with the 3.3V output. Margining function is provided for the user who wants to stress their system by varying supply voltages during testing. Integrated input and output filters enable a simple PCB layout. Only bulk input and output capacitors are needed.

    Product Details

    Demonstration circuit DC1041A-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.
