WEBENCH® Tools/LM74670-Q1: Can LM74670-Q1 be used in POE device for class 4?

Hi Nuri,

POE device operating voltage is 48V, LM74670-Q1 will not work due to the 42V limitation during reverse condition.

Could you share more details of the requirement in terms of end use, operating voltage and current.

Regards,

Kari.

I want to design a POE for IoT camera along with 24 VDC adaptor. The camera cequries 5V-4.25A power. It will have adaptor prioriity. 

Currently I have completed following design. Since I am a non-electronic proffesion, I am not to sure that details are complete! Would it be possible for you to check it for me?POE with ADP 24 VDC (5V,4.25A).pdf

Hi Nuri,

I have looked into the design pdf shared, but could not get your requirement on where you plan to use LM74670-Q1?

Is it for reverse polarity protection at the 24V adapter input?

Kari.

I wanted to use LM 74670-Q1 as a bridge rectifer after etherent transformer (L1) as seen in its data sheet, Later on I come across with the TPS2372-4EVM-006 Evaluation Module (Rev. A) and used its bridge recrifer.as reference.
