Tool/software:
Hello.
Input power drop occurs when four TPS1H200A-Q1 products are turned on simultaneously.
Changing from four to two TPS1H200A-Q14 reduces the input voltage drop.
I would like to ask why the voltage drop occurs and what method should I use to improve it.
Attached is the measured waveform and circuit configuration.

The circuit configuration was configured like a data sheet.
