Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 , TL431LI Hi,
Is it possible to use TL431LIBCDBZ as an alternative to U3 TL431ACDBVR in PMP8803?
I'm using the TL431LI part elsewhere in my design so I'd like to use this throughout. With the…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 Hi,
I'm testing the PMP8803 design and I'm finding I'm only getting an output of 7.8V under no load rather than 12V as per the design.
The only fix I've found is by reducing the…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 Hi,
in the schematic of PMP8803 REV A the output is 12V at 1A, but the title of the page is "LOW COST 10W POE CONVERTER".
what the right? this schematic for 12W or 1 0W max?

Hi
Is there any peripheral reference design for 802.3af 13W with TPS23754? Due to board space issues,
if there are…
Part Number: TPS23753 PMP88803, 12V 1A Unstable at no load. But when the current is 6mA, the output voltage is normal. please help to solve the problem.
Hi Parag,
Thanks for your patience.
I have went though the schematic. My major concern is there seems has no valid isolation in your current circuit. Please see the nodes in red cycle is from primary side and in green cycle is from secondary side. They…
Part Number: AM625 Other Parts Discussed in Thread: PMP22806 , TPS23731 we have requirement of 12Volt [12W to 15W] POE Supply.
we need your support to design Power Oring for POE & DC supply [Priority will be POE]:
We are providing both POE and DC Supply…
Hi Matt,
Got it! Sorry that I did not find a TPS2375 reference design with isolated converter.
Here is two flyback boards you can refer:
13-W rated flyabck, TPS23753A based. You can refer the power MOSFET / flyback transformer selection. Besides, you…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 Hi, We have a POE design based off PMP8803. We are currently failing the conducted emissions testing.
We have found the cause to be down to the slew rate of the main switching FET and increasing…
