demo system.

1. Download and install the LTpowerPlay GUI:

www.linear.com/ltpowerplay

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 DC2198A 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.

5. Ifmultipleboardsarebeingpowered,connecta+12VDC

power supply with >0.5A capacity to the VIN input jack

of the DC2198A.

6. Launch the LTpowerPlay GUI.

a. The GUI automatically identifies the DC2198A and

builds a system tree. The system tree on the left

hand side should look like this:

Note: For multiple board arrays, the GUI automati-

cally ensures each device has a unique address. In

this scenario, it is recommended at this

point to store these addresses to NVM

(EEPROM)byclickingthe“RAM->NVM”

icon in the toolbar.
