We have designed custom carrier boards for the Jetson AGX Xavier with a 72W Switching Regulator. We now face the issue that when the Module is powered on by VIN_PWR_ON, there is a dropdown of the voltage due to the high current necessary for the module and then the Xavier is not powering up. We use the pushbutton IC circuit from the design guide.
Can you number the inrush current for SYS_VIN_HV and MV? How many capacitors do you suggest to be placed in each power rail to the module? Is there any thing else to consider?
