MP5990+MP5991 parallel with different input voltage condition

Applications
1
  1. If I use these (MP5990+MP5991) for differencet Vin source when the Vin difference with in 20% range, how the chipset is working?
  2. I try to work these with different Vin condition and want to merge Vout to have current merging.When the one of chipset reaching current limit condition, how the Vout wave form of each chipset looks like when I add ideal diode between chipset Vout and Vout combine Node?

Hello,

According to the typical application, the Vin should be connected to the same source. As for connecting the outputs together, please connect them in the following manner as shown below:

There is a more detailed reference for the schematic shown with the following evaluation board: EV5990-5991-V-5PHASE-00A | 16V, 50A, Hot-Swap Intelli-Fuse Solution Evaluation Board | MPS

Let me know if there are any specific questions with this configuration.

Best,

Krishan
