DEMO MANUAL DC2269A-A

LtpowerpLay software Gui

LTpowerPlay is a powerful Windows based development 

environment that supports Linear Technology power sys-

tem management ICs, including the LTM4675, LTM4676, 

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 pres-

ent) 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 and DC2086A USB-

to-SMBus controller to communicate with one of many 

potential targets, including the LTM4676, the LTC3880, 

LTC3882 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:
