Ltpowerplay softWare Gui

LTpowerPlay is a powerful Windows based development 

environment that supports Linear Technology power 

system management ICs and μModules, including the 

LTM4675,  LTM4676,  LTM4677,  LTC3880,  LTC3882, 

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 LTM4675, 

LTM4676,  LTM4677,  LTC3880,  LTC3882,  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 documenta-

tion. The LTpowerPlay software can be downloaded from:
