THERMAL IMAGE
An example thermal image shows the temperature distri-
bution on DC2824A-A. The test is done in still air at room
temperature (23°C). Figure 6 shows a thermal image of
DC2824A-A operating at 12V

LTM4676, LTM4677, LTM4678, LTM4680, LTM4700,
LTM4664, LTC3880, LTC3882, LTC3883, LTC3884,
LTC7880 and LTC7131-1. The software supports a variety
of different tasks. You can use LTpowerPlay to evaluate
Analog Devices ICs by connecting to a demo board sys-
tem. LTpowerPlay can also be used in an off-line 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
DC1613A USB-to-SMBus controller to communicate
with one of many potential targets, including LTM4675,
LTM4676, LTM4677, LTM4678, LTM4680, LTM4700,
LTM4664, LTC3880, LTC3882, LTC3883, LTC3884,
LTC7880 and LTC7131-1’s 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. The LTpowerPlay
