Part Number: TPS23757EVM Other Parts Discussed in Thread: TPS23757 , TL431 Hi Bro,
Recently we designed in TPS23757 into our application. But now the IC TPS23757 creats much heat and output voltage is 5.6V. Even we adjust resistor R32 and R34 value…
Part Number: TPS23757EVM Hi E2E,
We measure the EVM of Q1 MOS, and find the glitch when gate falling.
Did you kindly let us know why had this glitch? Did have any risk?
Part Number: TPS23757EVM Other Parts Discussed in Thread: TPS23757 , TPS23758 , TIDA-00617 , Hi E2E,
We use TPS23757 EVM to design.
Could you let me know what key SPEC of diode?
Part Number: TPS23757EVM Other Parts Discussed in Thread: TPS23757 , Hi Sir,
In TPS23757 EVM schematic and datasheet, it shows there has gate1 for main NMOS switch and gate2 for senconary NMOS switch topology.
From datahseet, it shows gate1 and gate2…
Part Number: TPS23757EVM Other Parts Discussed in Thread: TPS23757 Hello guys,
One of my customers is going to use TPS23757 for their new POE products.
Also they will refer to the schematic in SLVU318B.
But they want to change the output voltage…
Part Number: TPS23757 Hi Darwin,
how would I measure Vds on the input and output FET using a standard scope given the different ground?
I am still working on the TPS23757EVM.

Hi Michael,
My apologies - I appear to have missed the word 'transformer' in the original enquiry. In the TPS23757EVM (slvu318b), I'm referring to part T3 Pulse PA0184.
I'm interested if there are any guidelines on how to calculate the minimum primary…
Part Number: TPS23757 Other Parts Discussed in Thread: , TPS23751 Hi Team,
In the TPS23757 datasheet, CS pin is used without pull-up to VB. Looking at TPS23757EVM user's guide, the CS pin is pulled up to VB. I could not find why pull-up is needed and…
Part Number: TPS23757 Hello, I have duplicated the design of the TPS23757EVM but it is not working. For space reasons I used a different gate drive transformer TDK/EPCOS B82804A0354A110 and the Wurth Elektronik 749 119 350 transformer. My board is making…
Hi Darwin,
the TPS23757EVM uses the Pulse PA0184 gate drive transformer. This transformer is rather large. Can we replace it with B82804A0354A110 ( en.tdk-electronics.tdk.com/.../b82804a.pdf ). I suppose it has similar parameters, but a bit smaller…
