LTpowerPlay SOFTWARE GUI

LTpowerPlay is a powerful Windows-based development 

environment that supports Analog Devices power sys-

tem management ICs, including the LTM4676A, LTC3880, 

LTC3883, LTC2974 and LTC2978. The software supports 

a variety of different tasks. You can use LTpowerPlay to 

evaluate Analog Devices 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 diagnos-

tic 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 LTM4676A, 

the LTC3880 and the LTC3883’s demo system, or a cus-

tomer board. The software also provides an automatic 

update feature to keep the soft-ware current with the latest 

set of device drivers and documentation. The LTpowerPlay 

software can be downloaded from:
