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:

Power  Products  visit  Help.  View  online  help  on  the 

LTpowerPlay menu.
