Functionality : direct parallel evaluation with multiple boards on ADP1055 EZ-LAB

Hi,

I try to put in parallel two galvanic insulated DC/DC converters, implementing ADP1055 on each.

How to proceed for voltage synchronisation and current sharing on the output without O'ring Diodes ?

This function is explained for the EZ-Lab evaluation board ADP1051-240Z-EVALZ UG-566.

But not explained on ADP1055-EVALZ_UG-710 :

"Connectors on the evaluation board provide synchronization, as well as share bus and PMBus™ interfaces, allowing direct parallel evaluation when multiple evaluation boards are connected in parallel to a common bus".

 

Is an application note available for this ?

 

Best Regards
