Part Number: TPS2372 Other Parts Discussed in Thread: TPS23880EVM-008 , USB2ANY , BOOST-PSEMTHR-007 , TPS23880 For a 60W POE application I used the TPS2372 to handle the negotiation, schematic for the relevant parts added as PDF.
The design works with…
Hi C.T,
Please see my comments below:
TPS23880 needs host to load sram code and do basic configuration though I2C even using auto mode. So SCL, SDAO and SDAI can't be left open and they have to be connected to a host.
You probably can get rid…
Part Number: TPS23881 Other Parts Discussed in Thread: BOOST-PSEMTHR-007 , I have some questions about how the TPS23881 will behave in auto mode with the following connectivity (see image) and the AUTO pin set to 124kOhm (2-pair, 15.4W). What will the…
Part Number: TIDA-00779 Other Parts Discussed in Thread: UCC28180 Tool/software: We have developed a 3kW PFC using TIDA-00779 reference. The design is for a fixed 395V PFC circuit. Apart from reference design we have used a single SiC MOSFET MW65R048M1H…
Dear Penny:
Sorry, Maybe I didn't describe it clearly.
I want design one port PSE injector product.(only one RJ45 port provide POE 60W output)
Please see the application drawing below.
I already reference for "TPS23881EVM-008"+"BOOST-PSEMTHR"…
Hello Hsu...nice to hear from you again.
The TPS2388 makes for a nice migration path to the TPS23880 and they are pin-to-pin compatible!
Please see the attached presentation, and watch our video on this topic here --> https://training.ti.com/tis-migration…
Part Number: TPS2372 Other Parts Discussed in Thread: TPS23881 , TPS2378EVM-602 Hi expert,
For this data page 20, does PSE use 2 different RJ45 or 2 different channels?
We concern that the VDD of 2 PSE channels, VDD1 of TPS2372(PD1) and VDD2 of…
Hi, Satoshi
1. Do you have PFC_OK signal for secondary stage?
2. Have check VCC of UCC28070 and PFC driver when PFC is delayed?
3. I saw the AC input voltage is very close to 85Vac, could you check you components design follow below calculator?…
Hi, Dushimutong
The signal on CSA is too small, could you check your components design with below calculation tool?
/cfs-file/__key/communityserver-discussions-components-files/196/5187.UCC28070-Design-Tool-8-15-08.xls
or compare your schematic…
Okay here is an example. I've left a bunch of the parameters as default as they are not important for what I want to highlight.
The design is configured for 200Vin_RMS min operation at an output power of 200 watts.
As configured there is a warning…
