LM5050-1: Lm5050 for power combination

Part Number: LM5050-1

I used to use lm5050 to combine two 48V power supplies, but now I want to combine three 48V power supplies. Can I use lm5050-1? Is it connected according to the following structure?

  • Hi Zhang,

    For ORing 3x 48V power supplies, the diagram shown above is recommended. 

    However, when using LM5050-1 for 48V application, we recommend to use the transient protection components as shown in Figure 24 of the datasheet.

    Also, please connect Vs pin to Input side for avoiding leakage current from OUT to IN (as mentioned in datasheet page 11, Note).

    Regards,

    Kari.
