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
end of USB cable into the I
2
C/SMBus/PMBus controller.
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
