    Identifying an SOT23-6 with marking JWF9R

    Hi all,
    Need help identifying an SOT23-6 with marking JWF9R
    Does anyone know what this chip is ?
    It can also help if someone can provide the datasheet of this chip.
    Thank you.

    It looks like it is a JoulWatt Tech JW5052C

      it is "JoulWatt Tech" chip but unfortunately not JW5052C .

          What does the ic do in the circuit? What tells you it is not the JW5052c

            So the markings for JW5052C are different "JWH6X", and he has "JWF9R".

              I know the markings are different, What does the ic do in the circuit? maybe it is a custom part number.
              You can provide him with the correct part number.

                  Have you any ideas about SOT23-6 that marked JWF9R ?

                    Re: Identifying an SOT23-6 with marking JWF9R

                    That's definitely a Joulewatt production , but the problem is , it comes in an evaluation board , so no specific datasheet can be found , other than digging in their evaluation boards and trying to assimilate details .. So , let me explain it one more different way .. It's not for sale as a one component , that's it .

                    You can find evaluation boards in their site , English and Chinese ones as well .

                      Here's an example of their evaluation boards , and it's built mainly around the "JW1130H , A current monolithic LED driver .. Notice the schematic inside the PDF ..

                        jiroy, thank you for your attempt to help me. I see that chip not for sale as a one component.

                          What seems to be the problem with U1? Also what is the number on U2 (JWC7, JW1221A)


                          The closest I can find is a Controller for adaptive 100/120hz current ripple removing.
                          It is a JW1251O marked JWE9.

                          I found your other post with additional pictures on monitor, so I guess you already have your answer.

                            I agree with "jiroy".
                            Probably chip JWF9R from evaluation board and it doesn't sell.
                            "R_J" - Your option with chip JW1251O is quite simillar to JWF9R.
                            If someone will find datasheet on JW1725O with output numbers and designations I'll be apriciated.
                            It's close enough with JWF9R as well.
                            Thank you.

                              Welcome Adomok7 ; I know you reached the same conclusions like I did .

                              JW1251O is a similar case to yours . No Marking code in its datasheet , because it's obvious it belong to another evaluation board . It's a pattern to this company . At the same time , which do not belong to some xxxxx evaluation boards , are given a marking code eventually ..But I feel you have done your research ...

                                Yes, I have done my research.
                                Thank you to all.
