Part Number: TPS23754 Hello expert,
I didn't see the OCP point set equation in datasheet for TPS23754 flyback topology. May you provide the guidance for the testing and set the value? Thanks a lot!

Part Number: TPS23754 Hi, TI experts
There is a request for technical inquiry from a customer regarding the use of TPS23754PWP in an RFID model.
The customer's RFID model operates by ORing the POE power and DC power to the TPS23754 to produce 5V output…
Part Number: TPS23754 Hi team,
If the TPS23754 is always in detect and classify state, will there be voltage output from the secondary transformer?
What is the internal DC-DC input voltage that will start the operation? Currently the customer's detection…
Part Number: TPS23754 Hi Team
Customer use TPS23754 to build the flyback PoE, the temperature of electrolytic capacitor connected between GND and Vc reaches 81.5 Celsius, which will greatly effect the capacitor life, can ceramic capacitors used in this…
Hi Henry ,
Sorry due to the format we could not do the layout review for you.
I will close this thread for now. Please reply or open a new thread if you have further questions.

Hi Grady,
Thanks for your patience.
Is there a reason to use 2KV for internal voltage?
- the 802.3 standard requires all PD & PSE provide isolation for all external conductors. Ethernet cable’s MDI leads should be included. 2 kV to meet the isolation voltage…
Part Number: TPS23754 We measured TPS23754 handshake waveform and found there is a current peak , pleas check attached picture for more detailed. We would like to know if this peak is noramal or abnormal behavior ? We found this peak on our board and TI…
Part Number: TPS23754 Hi Dear,
The customer made a circuit board using TPS23754, and the schematic diagram is as follows.
TPS23754_1_230600.pdf
1-During the test, it was found that the output 12V 2A was normal, but the efficiency was only 82%, and the…
Part Number: TPS23754 Hi
I want to get a review of the SCH, PCB pattern.
My customer doesn't want to disclose the circuit, so I want to deliver it personally.
Please let me know your email address or any other way.
Thanks
