Part Number: TPS23754 Other Parts Discussed in Thread: TPS23756
Tool/software:
Hello TI:
I am planning to use a PoE PD controller which needs to support up to class 4, and I am checking the differences between TPS23754 and TPS23756, in the datasheet…
Hi Shermen,
Thanks for your patience.
For C11 = 47uF or 22uF
shermen fang said: From FAE/ Ian and you said that " 25.5W 推薦33-47 uF. 22uF 比較worst的250us 0-current transient不行,但99.9%的情况影響不大。"
Yes this is for the C11: 33-47uF is recommended to fully…
Part Number: TPS23754 Other Parts Discussed in Thread: UCC2897A Tool/software: Dear Team,
Hello, I would like to inquire about the secondary-side synchronous rectification N-MOSFET (Q4) and the N-MOSFET (Q1) that controls it in relation to the TPS23754…
Hi shermen,
Thanks for your patience.
The calculation does not consider capacitance changes with higher voltage (DC bias).
I think other parts of your concerns about caps are answered in " ">e2e.ti.com/.../5715484
We could not provide personal…
Part Number: PMP22301 Other Parts Discussed in Thread: TPS23730 Tool/software: We are referring to the PMP22301 reference design to develop a 30W (24V/1.25A) PD based on the guidelines outlined in SLVA305C, using the POE300F-24L_ transformer.
According…
Part Number: TPS23754 Other Parts Discussed in Thread: TPS23731 Tool/software: Hi TIer,
May I know the TPS23754/6/1 can archive the line undervoltage soft-stop protection by external circuits? please help provide the reference circuit.
we need option…
Hi Michael,
Thanks for your patience.
Michael Gilge said: My question is, what could be the reason for not having the T2P go low when adapter power is present and the ADP-pin is higher than 1.5V?
Except the faults like over temperature, or transients during…
Part Number: TPS23754 Tool/software: Hello everyone,
Is there any 24V reference design for TPS23754? I want to design a 24V 30W PoE circuit and I am very new in this PoE world.
I've checked one reference design but I think the PoE transformer is now…
Part Number: TPS23754 Other Parts Discussed in Thread: PMP22301 Tool/software: Hi
I am looking for a PoE PD with dual outputs of 24v and 3.3v using the TPS23754. I have not found the right transformer for this. So far the closest option is the JA4372…
Hi Sijo,
This transformer is for flyback only. May I know if you also changed the circuit from forward converter to flyback converter? If so, could you share you updated schematic.
Sijo Augustine said: Flyback can also use, if there is a design having 12V…
