DESCRIPTION
DEMO MANUAL DC2450A
LTC2936
Programming Board for Programmable Hex
Voltage Supervisor with EEPROM
The DC2450A programming board contains the circuitry needed to program and verify the EEPROM of the
®
2936. This is its sole purpose. The LTC2936 comes
LTC
in either a 24-pin SSOP or a 24-pin QFN package. The
DC2450A-A supports the QFN and the DC2450A-B sup
-
ports the SSOP package.
The LTpowerPlay™ GUI stores configuration settings into
the LTC2936 EEPROM. Download and install the software
from this location:
http://www.linear.com/ltpowerplay/
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
DEMO MANUAL DC2450A
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 con
necting 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

erPlay utilizes the DC1613 I
C/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
drivers and documentation. Download the software from
