GENERAL  

The LGA50D evaluation board (LGA50D-EVAL-KIT-JLPJ, Revision AU) allows the user to 
test and investigate the performance of the LGA50D non-isolated module.  

Within the kit there are the following items: 

-  The evaluation board equipped with 2 LGA50D modules 

-  The Artesyn PMBus interface dongle 

-  The PMBus to USB interface cables 

 

Fig. 1 – LGA50D evaluation kit 

This equipment allows you monitor and control the modules via your computer, or you can 
apply settings to the modules by hardware configuration.
