LTpowerPlay SOFTWARE GUI

LTpowerPlay is a powerful Windows-based development 
environment that supports Linear Technology power sys-
tem management ICs, including the 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 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 LTC3880 and 
the LTC3883’s DC2052A 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:
