    Hi liekwang! or example. For smd, discrete 1206, for LT1057. No test. there will be comments that can be corrected ) SD2000_1_al_new6.rar

      Hi Andrei, yep I m already using tantalum capacitors as mentioned.
      I will do some updates and by the end of the week I will share my results.

          Hi Andrei, I broke one fet the IRF710, once I receive spares I will share all waves for each TP.
          Thx

            thank you sir did you refer from the ZED scheme as there was no mistake

                Hi liekwang,
                Please refer to the below link, it's for giving replacement that I'm using for transistors fets...

                        • Hello Andrei

                          Yes the signal is supposed to be there although we prefer that it wasn't,mosfets have what is called capacitance,as you may know,so the flyback voltage travels through this
                          capacitance and appears on the source terminal,the diode on the source will clip this signal to its forward voltage drop,because the capacitance is small the charge from the flyback voltage will also be very small.
                          As we source components like receive fets we like to aim for low capacitance but that comes at a cost of increased resistance,the trouble with that is we like to keep the resistance low as
                          well so then it becomes a bit of a juggling act,a mosfet i like to use for a receive fet is a ZVN4525G

                          Cheers....

                          • Thanks ZED! And what transistors do you use p-channel instead of ZVP4105

                            • SI1021R but its in a very small smd package.I used to use TP0202K but there obsolete now.

                              • Have you trying to use conventional mosfets ? IRF740 , IRF9640 ??
