Analog Devices Inc. EVAL-LTM4719-AZ Evaluation Board
Analog Devices EVAL-LTM4719-AZ Evaluation Board was developed to quickly and easily demonstrate the LTM4719. The LTM4719 is a 42V dual input, 150mA synchronous buck power µModule® (micromodule) regulator with an integrated battery health monitor and a low-dropout linear regulator.
The ADI EVAL-LTM4719-AZ has a wide operating input range of 2.4V to 42V, supporting a seamless transition between the two separate input power sources. The output range is 1V to 4.2V and can source up to 150mA of continuous output current.
The EVAL-LTM4719-AZ can be connected directly to a PC at P1 utilizing the DC1613A I2C/SMBus/PMBus dongle. The LTpowerPlay® enables users to run a graphical user interface (GUI) and format a battery state of health (SoH) monitor.
LTpowerPlay GUI Software
LTpowerPlay is a powerful Windows-based development environment that supports Analog Devices Power Management ICs using each device's specified Demo Board. LTpowerPlay can also be used in an offline mode (with no hardware present) to build multichip configuration files that can be saved and reloaded at a later time.
LTpowerPlay can function as a 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. The software also includes an automatic update feature to keep the software current with the latest device drivers and documentation set.
