TPS543B20: Connect VSHARE/ISHARE/SYNC pin together when two TPS543B20 are in standalone mode

Ann_Lien

Part Number: TPS543B20

Hello expert,

My customer would like to check if we can connect VSHARE/ISHARE/SYNC pin together when two TPS543B20 are in standalone mode. Since we would like to use master/slave mode and standalone mode in the same schematic. Please kindly help to confirm if we can connect these pins together when two TPS543B20 are in standalone mode. Thanks a lot!

Best regards,

Hi Ann,

You should not connect VSHARE/ISHARE in standalone mode. You can use a 0 ohm resistor to connect them and have them NOT-MOUNTED for standalone application and MOUNTED for dual phase applications.
