DEMO MANUAL DC2277A

Quick start proceDure

Demonstration circuit 2277A makes it easy to program

and verify the EEPROM contents of the LTC3886 in the

UKG package.

1. Make sure jumpers are in the following positions:

JUMPER

POSITION FUNCTION

JP1

OFF

Write Protection of LTC3886

JP2

ON

Write Protection of Identification EEPROM

2. Open the lid of the socket. Verify there is an LTC3886

inside. See Figure 2.

3. Close the lid. It will snap into place.

NOTE: Removal and insertion of the IC should be done

with either a tweezers or a vacuum suction device.

4. Plug one end of the USB cable to your PC. Plug other

5. If you have a DC1427A, plug the ribbon cable into J1.

If you have a DC1613A, plug the ribbon cable into J2.

See Figure 3.

6. On your PC, launch LTpowerPlay. LTpowerPlay will

identify the DC2277A and launch the appropriate GUI.

See Figure 4.

NOTE. You will see an Under Temperature (UT) Fault.

This is normal since the temperature sensing pin is

grounded. Ignore this fault at the moment.

7. Change the GUI parameters according to your system

requirements. Or, you can click

button to open an

existing project file.

8. After you finish the design, click

to save the project
