Other Parts Discussed in Thread: PMP21318, UCC2897A, TPS2373
Hi,
1.My design is based on 8228.PMP21318_RevA(001)_Sch,please refer to the attachment for details.
2.In the test,the voltage of vc_in is half that of VDD ,if VDD=40V,VC_IN=20V.then the vc_out =20V.But the maximum voltage of VDD of UCC2897A is 16.5v.Is there something wrong with the transformer?
3.In the test,pd is not recognized by the pse (802.3 at).Rclsa=63.4 and Rclsb=90.9,is there something wrong with the CLSA and CLSB?
4.I have a question to confirm,is the switch of UBNT us-xg-6poe compatible with this PD? AND what do I need to set?
Looking forward to your reply!
Thanks!
