LMZ13610: Whether the schematic diagram of power chip is correct？

Hello

Your schematic looks good to me.

I do see two things to keep in mind:

1.  You have no input filter damping.  The large input filter inductance

can resonate with the ceramic input capacitors and may cause excessive ringing

and possible overvoltage on the input.  It is best to use a small aluminium electrolytic capacitor

on the input to help damp this input circuit.  The ESR of the electrolytic capacitor will provide damping.

A 22uF or 47uF may be all that is required. I have attached an application note here that may help.

2.  It is is good idea to leave a place on the PCB for a capacitor across the top feedback resistor.

This may be needed to provide good loop phase margin and/or good load transient response.

It can be DNP until if and/or when you need it.

Also, we are happy to review your PCB layout when it is ready.

Thanks
