Part Number: TPS7A78 Hi Ti
I understand that the resistor Rs is required to limit the surge current into the AC+/- pins when the device is first powered from the AC supply. The limiting current is 2.5A from the datasheet.
Our application will run from…
Part Number: TPS7A78 Other Parts Discussed in Thread: CC1101 Hi Ti
Thanks for your help with my two previous questions. I have another one I'm afraid.
I'm looking in detail at the 3.3V output variant of the TPS7A78. From the datasheet I think the…
Part Number: TPS7A78 Hi
Could you please let me know your recommended Rs/Cs value for the following conditions?
Also, how will we select those values?
ACin = 80Vac ~ 276Vac
Bridge : Half bridge

Part Number: TPS7A78 Hello,
Would you happen to have please the symbol and footprint of the PTPS7A7833PWPT part in orcad format (sym, dra, pad, step, etc)?
Thank you.

Part Number: TPS7A78 Regarding TPS7A78, I see in the datasheet that the highlighted input voltage range is 70 to 270VAC. I understand that Cs and Rs affect the maximum AC supply voltage, so:
Can this device support 347 to 480VAC input with a specific…
Part Number: TPS7A78 Hi
Could you please let me know the value of applied voltage to Cscin. (I know the recommended voltage rating is over 35V. I want to know the actual voltage value.)
Customer plan to use the Half-bridge configuration.
In this case…
Part Number: TPS7A78
Hello,
I need to supply a load with 5V/0.3A. I see in the datasheet that the maximum allowed is 120mA.
Is it allowed to connect 3 units of TPS7A78 in parallel?
Can I share the Cs capacitor with all the units?
Do TI have a smaller…
Part Number: TPS7A78 Hello
My customer is evaluating TPS7A78EVM now. They have a question.
Could you please support the following question?
Customer comment is below,
We do a slow-down test on TPS7A78EVM (Half-bridge mode) and can't understand a waveform…
Part Number: TPS7A78 Hi team,
On the datasheet of TPS7A78, section 7.3.7, I found that the Vscin=4*(Vldo+0.6V)-2.5V, so the Vscin should be around 20V.
But according to the block diagram, SCIN should be the output of half bridge/full bridge rectified…
