Thank you sir for the PCB layout. It is probable that the constructor will be forced to compromise, using a significantly lower quiescent current than suggested just to maintain a sensible heatsink size and temperature.

Use a single transformer may be torroid one capable of 20amps capacity. While this is true to an extent, it is obvious that it is not a general rule upon which one should rely in all circumstances. The only way that you can be assured of safety is to keep the peak dissipation well below the claimed maximum, thus minimising the die temperature.

I want to add a short circuit or overload protection fuse in this system, suggest some links to get some idea about this. While this is good for switching reduced lossesit also ensures that they are less suited to linear operation.

Something must be terribly wrong with my circuit. If one cell has a slightly lower V GS than the others perhaps due to microscopic variations in the silicon it will take more of the total current.

Can I use 20pf in place of c4 n c5?? I suggest that high voltage, relatively low current devices are preferable to the reverse, as they will have an inherently higher R DS onand therefore a lower inflection point. I had to guess and check with my ammeter to get a good value. If it is ok replace link with say 2k2 pot and set the current through the fuse for 50 to 60 mA.


Do the tweeter have impedence? The lower impedance of the driver stage the better. Try this W Hi-Fi mosfet Amplifier http: The multiplication factor of gives the headroom needed for accurately reproducing a square wave or high frequency sinewavesince the gate driver needs a lot of current to quickly switch the MOSFET from OFF to ON.

It is just easier to use more linear devices.

Also note the capacitor in parallel with R7. Power amplification stage based on Q7 and Q8 which operates in the class AB mode. The resistors seems to be fine. Design a compact PCB layout with feedback taken from as close as possible to the load terminal. If we look at these complementary device data sheets, we will see very different figures for current capability, on resistance, and, most importantly, gain or forward transconductance.

I mean class A. Note that the article above does not address this potential failure mode, nor do many othersand your only choice is to find MOSFETs where the thermal ‘changeover’ occurs at the lowest possible drain current.

Can i use it as a subwoofr amp? It’s worth noting that the TO package is useless regardless of what’s inside for getting rid of any more than about 20W worth of heat, unless extraordinary care is taken with mounting.

Iffp9240, the two are directly related, so the point is moot. But if we use a matching tool, we will find that the gain varies considerably from the actual devices vs. Adjusting the bias to 1 amp removes nearly all distortion, yet now we are approaching a heater Do the calc, and see for yourself.


This much is true, but this alleged ‘benefit’ is actually completely useless in a linear circuit. The article is intended to describe the design process and how to work around the inherent non-linearity of vertical MOSFETs, and is not intended to be a construction project.

It is a better practice to use separate heat sink for each different application. A compact and nicely wired PCB should decrease distortion even further.

Thanks for the help. Likewise, the peak current should also be much lower than the rated maximum. Alright, now for some explanations.

The update below has some important information that I recommend you read thoroughly and make sure you understand before settling on the use of HEXFETs in your next amp project. This Hi-Fi amplifier circuit is suitable iirfp9240 a lot applications like general purpose amplifier, guitar amplifier, keyboard amplifier.

Well, that is the easy route to take for designing an output stage.

On top of this, there is a much larger voltage loss If every thing is oK it should stay alright if the fuse blows indicates something wrong in the wiring. This amplifier will burn. It stabilised fairly quickly because the heatsink prevented further possibly damaging heat levels, but datasheer two MOSFETs in parallel, the current between them was different, and more importantly it remained different, even as they became hotter.
