DC1508B - Demo Manual

DEMO MANUAL DC1508B
LTC2974/LTC2975/LTC2977/
LTC2978/LTC2978A
Programming Board for PMBus
Power System Managers
Description
The DC1508B programming board contains the circuitry
needed to program and verify the EEPROM of the LTC2974,
LTC2975, LTC2977, LTC2978, and LTC2978A. This is its
sole purpose. The DC1508B is shipped with a clamshell
style programming socket installed. The EEPROM contains
the factory default configuration. The LTpowerPlay™ *.proj
file that corresponds to the factory default can be found
in the GUI.
To properly program and verify the contents of the EEPROM,
download and install the LTpowerPlay software (GUI).

You also need a Linear Technology DC1613 USB to
SMBus/PMBus Controller.

LTpowerPlay GUI Software
LTpowerPlay is a powerful Windows-based development
environment that supports Linear Technology Power
System Management ICs with EEPROM. The software
supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting
to a demo board system. LTpowerPlay can also be used
in an offline mode (with no hardware present) in order to
build a multichip configuration file that can be saved and
reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features. It becomes a
valuable diagnostic tool during board bring-up to program
or tweak the power management scheme in a system or to
diagnose power issues when bringing up rails. LTpowerPlay utilizes the DC1613 I2C/SMBus/PMBus Controller to
communicate with one of many potential targets, including
the DC1508B programming board or a customer board.

DEMO MANUAL DC1508B
Quick Start Procedure
The DC1508B programming board makes it easy to
program and verify the EEPROM contents of the device.
1.Place jumpers and switches in the following default
positions.
WP:
OFF
ASEL1:
L
ASEL0:
L
S1:
OFF
4.Close lid. It will snap into place. See Figure 5.
NOTE: Removal and insertion of the IC should be done
with either tweezers or a vacuum suction device, and
also with the power switch S1 set to OFF.
NOTE: By default, the ASEL jumpers are both set to low.
If you wish to program a device with an offset address
other than 0x5C, adjust the ASEL jumpers appropriately.
Consult device data sheet for details.
2.Connect the DC1613 controller to your PC. Plug the
ribbon cable into connector J1 of the DC1508B programming board.
3.Open the socket lid. Place the IC inside with pin 1 located
in the upper left corner. See Figure 4.
Figure 5. DC1613 Ribbon Cable Attached and Lid Closed
5.Set the power switch S1 to the ON position. The VDD33
LED will illuminate, indicating the on-chip regulator is
providing internal power.
6.Launch the LTpowerPlay software from your PC. Select
Utilities>Programming Utility from the menu. Click
“…” next to the selection box and select a .proj file to
program the device.

Quick Start Procedure
7.LTpowerPlay is ready to program/verify the device.
a. Click the Program and Verify button, and wait for the
process to complete.
8.Prior to removing the device and programming another,
power must be removed from the device. Set the power
switch S1 to the OFF position. Open the socket lid.
Remove the device with tweezers or a vacuum tool.
The USB ribbon cable may remain connected to the
programming board.
9.To program another device, repeat Steps 3 through 5,
then Steps 7 and 8. LTpowerPlay’s Programming Utility
does not need to be closed.
b.After the process is complete, you will see Successfully
Programmed and Verified Device in the status bar at
the bottom.
