Analog Devices LTM8074EY | Demoboard DC2753A

Description

Demonstration circuit 2753A features the LTM®8074EY μModule regulator, a tiny high performance high efficiency step-down regulator with Silent Switcher® architecture. DC2753A has an operating input voltage range of 3.4Vto 40V and is able to provide an output current of up to 1.2A. The output voltage can be programmed from 0.78Vup 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 demo board also has a conducted EMI filter installed. To use the con-ducted EMI filter, the input should be tied to VEMI, not VIN. 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
