Hi.
I connect TPS23753AEVM-001 to NETGEAR GS305P-100JPS, but it doesn't work.
The PoE startup sequence is working fine, but it resets after 360msec.
The waveform vdd-vss is attached.
Please teach reason and solution.

Hello,
Please try adding at least 1W of load to the output of the DCDC converter.
Thanks!

Thank you for your support.
I connect 20ohm, it worked correctly.
The reference is cannot used small loads?
I understand the problem is MPS DC current 10mA @ 48V.
It is necessary to connect the corresponding load (including PD circuit).
Thank you.
