DESCRIPTION
LTC2937
Programming Board
The DC2347A contains only those functions necessary
to safely program and verify the LTC2937 configuration
EEPROM. It serves no other purpose. The DC2347A holds
the LTC2937 in a clamshell socket for convenient access
andreplacementofparts.TheLTpowerPlay™GUIsoftware,
running on a PC, provides a simple interface to program
and verify the EEPROM with a user supplied configuration.
What Can You Do with The DC2347A
• Program the contents of the EEPROM with your project
or HEX file.
• Verify the contents of the EEPROM against your project
or HEX file.
• Verify the contents of the EEPROM against factory
defaults.
DC2347A
• Program and Verify EEPROM for the LTC2937
• Easily Change Parts with the Clamshell Socket
• Simple Interface to the PC Using LTpowerPlay

QUICK START PROCEDURE
The DC2347A system makes it easy to program and verify
the contents of the LTC2937.
1. Download and install the LTpowerPlay GUI:
http://www.linear.com/ltpowerplay
2. Remove the DC2347A board from the ESD protective
bag and place it on a level surface. Connect the DC1613
I2C/SMBus/PMBus Controller to the DC2347A board
using the 12-pin ribbon cable.
Set the jumpers ASEL1, ASEL2, and ASEL3 for the
desired device I2C address. Note that each project file
contains a fixed device address, which must match the
ASEL jumper settings on the board. See the LTC2937
data sheet for a discussion of device addressing.
Set the WP jumper to OFF.
Set the POWER switch to OFF.
3. Connect the USB-to-I2C/SMBus/PMBus Controller to
a USB port on your PC.
4. Insert an LTC2937 part into the clamshell socket and
verify that it is upright and not upside-down in the
socket. Close the lid; it will snap shut. Only remove
and replace ICs in the socket when the POWER switch
is OFF.
5. Applypower to the device by sliding thePOWER switch
to ON. When the part receives power it powers-up its
3.3V VDD pin, and LED1 will illuminate green. If no
part is installed in the socket, or if the part is up-side
down, the LED will not illuminate, and programming
is not possible.
6. Launch the LTpowerPlay GUI. The GUI automatically
identifies the DC2347A and launches the appropriate
interface protocol.
7. If the Programming Utility does not launch automati-
cally, select LTpowerPlay→Utilities→Programming
Utility from the menu.
8. Click “…” and select a project file to program the de-
vice. Ensure that the ASEL jumpers match the device
address in the project file.
9. Click “Program and Verify System” to program the
device. Upon success, the status bar at the bottom will
turn from yellow to green and indicate “Successfully
Programmed and Verified System!”
10. After programming the LTC2937, set the POWER
switch to OFF and remove the part from the socket.
Repeat steps 4 to 9 with additional LTC2937 parts as
necessary.
