Hello Anson,
The output filter will depend on the topology and implementation of the design. Can you please provide a schematic for your design?
What I can say is 250kHz is the typical switching frequency of the primary FET. I try to think of identifying…
Part Number: TPS23754 I have a customer that would like to follow the example on page 13 of this app note ( Advanced Adapter ORing Solutions using the TPS23753 ) to have two power supplies OR'ed together (PoE and DC/DC).
Is this the best approach…
Tateo-San, The following two TI designs, available online, are close to your requirements.
12V@0.4A, Isolated Flyback = http://www.ti.com/tool/PMP464
2V@0.6A, Isolated Flyback = http://www.ti.com/tool/PMP5595
Both are older reference designs and…
Part Number: TPS23754 Other Parts Discussed in Thread: TPS23753 , TPS23753A , TLV431A Hi all.
I am trying to bring up a board based on the '420 evem, using the optimized components in SLVA475, the efficiency optimized synchronous flyback converter…
Hi Thomas
Thank you very much for all the information.
The controller TPS23753 related application notes seems te be on a high level. Much better than the documents available for the LM5071. With that I think it should be no problem to do our own…
Hi Tateo,
Thank you for your question. We do not have a 24V output design using the TPS23753A, however, we do have a 19.5V / 0.6A design that can be modified for 24V. You can find the BOM and Schematic on a previous E2E post here . For making changes…
Other Parts Discussed in Thread: TPS23753 , TPS23770 , TPS23753A , TPS23750 , TPS23757 , TPS23757EVM , TPS2376-H Hi.
I need to design a POE PD classification + isolated power converter stage for a load which is around 12 W at 5V.
As this is high load…
Hi Gergely,
So powering from either J6 or P7 don't work, right?
The DC/DC controller datasheet can be found at: www.ti.com/.../tps23753.pdf
Can you also check TP6, TP8 and TP10 and compare between the working and the non-working board?
Hi Darwin,
If I want to design TPS23753 (802.3af,PD,12.95W) with giga LAN, can I use the same source part of RJ45 with transformer which design in TPS23756(802.3at,PD,25W)?
Does diode bridge also use the same source (B1100) in TPS23753 and TPS23756…
