Quick Start Procedure - Linear Technology DC1709A Manual

DEMO MANUAL DC1709A

Quick start proceDure

Demonstration circuit 1709A makes it easy to program
and verify the EEPROM contents of the LTC3880.
1. Make sure jumpers are in the following positions:
JUMPER POSITION FUNCTION
JP1 Off
JP2 On
2. Open the lid of the socket, SKT1. Verify there is an IC
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 the
other end of the USB cable into the I
controller.
5. If you have a DC1427A, plug the ribbon cable into J1
(see Figure 3). If you have a DC1613A, plug the ribbon
cable into J2, as shown in Figure 3 and Figure 4.

6. On your PC, launch LTpowerPlay. LTpowerPlay will
identify the DC1709A and launch the appropriate GUI
(see Figure 5).
NOTE: You will see an undertemperature (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 open an existing project file
by clicking this button:
8. After you finish the design, save the project file by

PROGRAMMING OPERATIONS
Disconnect the USB cable from the DC1427A/DC1613A
before removing or inserting a LTC3880 into the pro-
gramming socket.
