Part Number: TPS23754 Other Parts Discussed in Thread: , TPS23756 Hi sir,
I have doubt about Tps23754 and Tps23754-1, Could you tell me the difference between them? By contrast, I found the datasheets are same. Thanks a lot.

Jenny
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 Dear,
1-The customer referred to the evaluation board of TPS23754 and made their own circuit board. Initially, there was a voltage output during testing. but during the testing process, there was no voltage output with a load…
Hi Jack,
Good morning!
We replaced TPS23754-1 by TPS23754.
Now we observe the chip works at lower voltage but it is still odd -
min VDD needed at boot up is 27.66V and min VDD after boot @ full load operation is 24.42V.
The data sheet clearly says the…
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…
Other Parts Discussed in Thread: TPS23754-1 Hello,
We are using the TPS23754-1 in a poe application and are having difficulty getting the external frequency sync function to work. My customer is concerned that the ~2V sync pulse at FRS could potentially…
Hi Ahmed,
Vin = 12 - 57 V (max PoE input) will normally be a challenging design for flyback converter.
At 12-V adapter input, the current on current sensing resistor may reach 1A. WIth 0.56R resistor, it can cause the CS pin voltage too high to clamp…

Dears,
We use TPS23754 as PD equipment, powered from PSE device. However, the peak value of the power-on current is too large, causing startup failure.
1. PSE powers on the self-developed…
Part Number: TPS23754 Other Parts Discussed in Thread: PMP6812 , PMP6672 , TPS23731 Hi all,
I would like to get advice about the most reasonable way to implement redundant power supply for my device by powering it via 2 DC power supplies and 1 PoE as backup…
