POE PD+DCDC non-isolated solution [Copy link]

 

Take MPS's MP8007 non-isolated solution as an example, Vin=48V, Vout=12V;
Is the following understanding correct:
① With VSS as the reference ground, Vin=48V, Vout=48V, VoGND=36V;
The voltage from Vout to VoGND is 12V;
② Is it necessary to connect VSS and PGND, and how to connect?
③ Is it necessary to connect VoGND and PGND, directly or with a capacitor bridge?
When VSS, PGND, and GoGND are directly connected, how do you understand the reference potential?

It is recommended to refer to the data sheet for wiring

If you have any questions, you can ask FAE for answers.

VSS PGND VOGND should not be simply connected together
