LM25119: Dual Phase not sharing current

user5782726

Part Number: LM25119

VIN: 24V

VOUT: 12V

IOUT: 30A

F:400KHZ

The interleaved two currents are uneven, one side 10A, the other side 20A.

The two parameters are exactly the same.

PCB symmetric layout

Up and down two current waveforms

This is the schematic diagram of the main circuit.

The parameters are not necessarily correct, but the parameters of the two roads are exactly the same.

I hope Qian Chen engineer can help me analyze.

Thank you very much.
