DC2450A - Demo Manual

DEMO MANUAL DC2450A
LTC2936
Programming Board for Programmable Hex
Voltage Supervisor with EEPROM
Description
The DC2450A programming board contains the circuitry needed to program and verify the EEPROM of the
LTC®2936. This is its sole purpose. The LTC2936 comes
in either a 24-pin SSOP or a 24-pin QFN package. The
DC2450A-A supports the QFN and the DC2450A-B supports the SSOP package.
The LTpowerPlay™ GUI stores configuration settings into
the LTC2936 EEPROM. Download and install the software

The DC2450A communicates with LTpowerPlay through
a Linear Technology® DC1613 USB to I2C/SMBus/PMBus
Controller.
What Can You Do with the DC2450A
1. Compare the contents of the device’s EEPROM against
any Project File. (Verify)
2. Reprogram the contents of the device’s EEPROM using
any Project File. (Program and Verify)

LTpowerPlay GUI Software
LTpowerPlay is a powerful Windows-based development
environment that supports Linear Technology Power
System Management ICs with EEPROM, including the
LTC2936 Programmable Hex Voltage Supervisor. 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 features an
offline mode to build a multi-chip configuration file for later
use with hardware. LTpowerPlay provides unprecedented
system level 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
SYSTEM TREE OF
ALL DEVICES
CONFIGURATION SETTING FOR
ALL DEVICES IN SYSTEM TREE
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 DC2450A demo system or a customer board.
The software also provides an automatic update feature
to keep the software current with the latest set of device
drivers and documentation. Download the software from:

Quick Start Procedure
The DC2450A programming board makes it easy to program and verify the LTC2936 EEPROM contents.
1. Place jumpers and switches in the following default
positions:
ASEL1: L
ASEL0: L
OFF
S1:
3. If using DC2450A-B, open the pinch contacts of the
socket by pressing down and holding the top of the
spring loaded socket frame. Place the IC inside the
socket with pin 1 located in the upper left corner. Slowly
release the top of socket frame, allowing contacts to
pinch together and grip IC leads. See Figure 5.
NOTE: By default, the ASEL jumpers are both set to
low. If you wish to program a device with an address
other than 0x50, adjust the ASEL jumpers appropriately.
Consult device data sheet for details.
2. Connect the DC1613 USB controller to your PC. Plug
the ribbon cable into connector J1 of the DC2450A
programming board. See Figure 4.
Figure 5. DC2450A-B and IC Installed
Figure 4. DC2450A-B with Open Socket
NOTE: Removal and insertion of the IC should be done
with either tweezers or a vacuum device, and also with
the power switch S1 set to OFF.

Quick Start Procedure
4. If using DC2450A-A, flip open the socket lid and place
the IC inside with pin 1 located in the upper left corner.
See Figure 6.
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. The
device programming utility shown in Figure 8 should
pop up automatically. If it does not then select the
Utilities>Programming Utility from the menu shown
in Figure 9.
