LTpowerPlay GUI SOFTWARE
LTpowerPlay is a powerful Windows based development
environment that supports Linear Technology digital power
ICs with EEPROM, including the LTC2974 and LTC2978
quad and octal PMBus power supply managers, and
the LTC3880 dual output PolyPhase
® step-down DC/DC
controller with digital power system management. 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 pres-
ent) 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 the LTC2974’s DC1978A demo system
or a customer board. The software also provides an au-
tomatic update feature to keep the software current with
the latest set of device drivers and documentation. The
LTpowerPlay software can be downloaded from:
