www.ti.com MSOP-8EVM-PDK Kit Operation
The MSOP-8EVM-PDK can be operated with a unipolar +5V supply, in which case an ac adapter or a lab
power supply can be used. When the MMB0 DSP is powered properly, LED D2 glows green. The green
light indicates that the 3.3V supply for the MMB0 is operating properly; however, it does not indicate that
the EVM power supplies are operating properly.
An ac adapter can be connected to barrel jack J2 on the MMB0. J2 is located next to the USB connector.
The adapter must output 6V to 9V dc. The connector must be sleeve-negative, tip-positive. It should have
a current rating of at least 500mA. Figure 5 shows the correct connections.
Jumper J12 on the MMB0 connects a wall-mounted power supply to the board. To use the wall-mount
supply, J12 must be shorted.
