LTpowerPlay Software GUI
LTpowerPlay is a powerful Windows based development
environment that supports Linear Technology power sys-
tem management ICs, including the LTM4676, LTC3880,
LTC3883, LTC2974 and LTC2978. 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 mul-
tichip 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 LTM4676, the
LTC3880 and the LTC3883’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
software can be downloaded from:
