Product Details

Demonstration circuit 2753A features the LTM8074EY µModule regulator, a tiny high performance high efficiency step-down regulator with Silent Switcher^® architecture. DC2753A has an operating input voltage range of 3.4V to 40V and is able to provide an output current of up to 1.2A. The output voltage can be programmed from 0.78V up to 15V. The LTM8074EY is a complete DC/DC point of load regulator in a thermally enhanced 4mm × 4mm × 1.82mm BGA package requiring only a few input and output capacitors.

The radiated EMI performances of the board (with EMI filter) are shown in Figure 6 and Figure 7. The demo board also has a conducted EMI filter installed. To use the conducted EMI filter, the input should be tied to V_EMI, not V_IN. An inductor L2, which is a 0Ω jumper on the board by default now, can be added in the EMI filter to further reduce the conducted emission.

The LTM8074 data sheet must be read in conjunction with this demo manual for working on or modifying DC2753A.
