TPS2384 - Recommended 48V isolated power supply

Other Parts Discussed in Thread: TPS2384

Hello everyone,

I'm designing a pcb using the TPS2384 quad PoE controller and I'd like to power it up with a 48V isolated power supply which could provide at least 2.4A, however I haven't been able to find one. Could someone please recommend me one, or at least put me on the right track?

Thanks in advance,

Alex.

Hi Alex,

Are you looking for an isolated DCDC reference design? what's the input voltage range? Thanks.

Best regards,

Penny

Yes please. The input voltage range is +9V to +20V DC.

Hi Alex,

Does this design work for you? PMP7324: 54V/2A/108W with 18-75V input

If not I will check with our design service team and find some for you. Thanks.

Best regards,
