Part Number: TPS23753AEVM-004 For 12Vout Application, IRF7855 N-Chan MOSFET (Q1) is impossible to find in stock. Will Si4190ADY work for this application. Vgs threshold is slightly different.
Hi Jieun,
Please see the measured power of TPS23753AEVM-004 ( www.ti.com/.../TPS23753AEVM-004):
48-V RJ45 input at open load condition: Vin = 48V, Iin = 14.03mA, Vout = 3.3V
12-V VDD-RTN adapter input at open load condition: Vin = 12V, Iin = 21.91mA, Vout…
Part Number: TPS23753A Other Parts Discussed in Thread: TPS55340 , TLV431 Hi--
We have a new prototype design with a PoE front end essentially copied from the TPS23753AEVM-004. When powered from a RTN referenced supply at 36V (this is all we have tried…

Hi,
Here’re some questions from customer about TPS23753A-004EVM.
1. For the original EVM which is synchronous MOS at secondary side, why it will be CCM even load=0A? What’s the gate turn on/off criteria?…
Part Number: TPS23753AEVM-004 Hi,
Reading the users guide for the TPS23753AEVM-004 board, I am looking at validating the operation at 5V under 10W load, with a 12V AUX input.
First, I will change the components listed in the BOM for 5V output operation…
Part Number: TPS23753AEVM-004 Hi,
I have a mysterious problem. I am using TPS23753AEVM-004 reference design for my PoE based power supply. I have both options. I will use wall adaptor or PoE PD as power supply input. The power section is working well with…
Hi Rob,
Thanks for your follow-up.
POE13P-24L looks good for 24-V ~500 mA application. The windings is
If you have a TPS23753AEVM-001, it looks easier to do some jump wires to only configure the secondary side.
If you have a TPS23753AEVM-004, it may…
Part Number: TPS23753AEVM-004 Other Parts Discussed in Thread: TPS23753A , TL431 , TLV431 I have a new design that is based on the TPS23753AEVM-004, but uses the suggested BOM changes for 5VDC. (a also used the design guide for the feedback side)
Fresh…
Hello Oleg,
Please review our TPS23753EVM-004
https://www.ti.com/tool/TPS23753AEVM-004
The TPS23750 is an active part at this time, but we cannot speak to the entire BOM since so many parts are sourced by other vendors.
Let me know if you have any questions…
