Ah I see. I am using a 1.2 x1.4cm heat sink.
You mentioned the "12W can be too much for this FET". Isnt the Mosfet IRF5210 rated for 200W at room temperature? So it should handle this? No? Correct me if I'm wrong kindly.
Also, what do you propose the solution then? How should I limit the...
Its mentioned here:

Also the 120 ohm load draws 0.4A and that is a stable current value, not inrush. The simulations show inrush of 0.3 to 0.4A max.

Sorry I could'nt get your point, kindly explain a little.

Hi all. I'm working on a load switch circuit that drives a capacitive load of 1000uF and a GAN transistor in parallel. The schematic of the circuit is attached. The input voltage is 50V and the Pmos being used is IRF5210. The simulations show promising results(also catering the inrush currrent...
Source connection is left open as this transistor is connected in a back to back common source configuration as shown below.
Also whose maximum rating are you talking about? The transistors? I am testing my setup in Airconditioned environment with fast speed fan.
Hi all.
I'm using LTC4367 for reverse polarity, OV and UV protection. I'm using the FDMD84100 Dual N channel Mosfets and the input voltage is 50V. However, when connected without any load, the output voltage is all OK at the beginning but then it gradually decreases towards zero. Also my...
Hello Everyone.
I am gonna design a Push-Pull dc dc converter converting 48V to 330Vdc based on the Tahmid's blog as below.
My questions are:
1) Do I have to use isolation in the feedback, for example through opto-couplers, to isolate the higher voltage secondary side from the primary side? Or...
Thankyou. :) Also, the inductance of the motor is 30mH. So, dont you think it will distort the waveform and drop hell of the voltag too? I am not regulating the dc dc stage right now either.

Yes, I isolated the ground point from the plug by using 2 pin connector.
Success IT IS I was successfully able to make my project working again. The problem was not of the filter or anything. It was the unproper grounding in the building I'm working at. The ground is giving a freaking 90V and I had to isolate my project from it. And it worked perfectly. :)
Now the...
I am currently using this combination.
I tried increasing the "C". But the output gets shortened dur to unknown reasons :/
(Also, yesterday I couldnt get the same results either, that is, everything was shortening out when the capacitor was connected. Then dont know after 4 hours of...
