demo system.

1. Download and install the LTpowerPlay GUI:

2. Remove the board from the ESD protective bag

and place it on a level surface. Connect the DC1613

I2C/SMBus/PMBus Controller to the DC2023A board

using the 12-pin ribbon cable.

3. Confirm that the CONTROL switch is set to the RUN

position.

4. Plug the USB to I2C/SMBus/PMBus Controller into a

USB port on your PC. The board should power up with

all power good LEDs and +5V LED illuminated green.

The USB-to-I2C/SMBus/PMBus Controller supplies

~100mA of current which should be sufficient for a

single demo board.

of the DC2023A.

6. Launch the LTpowerPlay GUI.

a. The GUI automatically identifies the DC2023A and

builds a system tree. The system tree on the left hand

side should look like this:
