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. For stereo you have to double the current of transformer. These current figures seem quite high, but keep in mind this current will only last a very short time compared to the signal, and virtually no current is needed to keep the devices either in the OFF or ON state.

What of the second breakdown effect that the manufacturers deny even happens other than in the very fine print? The current through Q5 and Q6 will be identical.

Set R1 at midpoint before powering up and then adjust it slowly in order to get a minimum voltage less than 50mV0 at the output. The current to reproduce a sinewave will be a bit lower, since it is a smooth curve, but this much headroom will drastically lower distortion.

The large notch is at the second harmonic, and the small bump to the right lrfp9240 the fourth harmonic.

IRFP – IRFP P-Channel MOSFET Transistor

One woofer, midrange and tweeter will be connected parallely to the one channel of stero amplifier, so I think two 8 ohms drivers can make 4 ohms load.

The amp works fine. If you are using 2 similar amplifiers yes with proper insulating kits you can use provided the sink is sufficiently big to take care of the generated heat. As it transpires, the design I was looking at was unsuitable for the intended datashedt, because the quiescent current iefp9240 to remove crossover distortion datashheet too high to be practical. Is good circuit have tested it and it works well the circuit is better for very high voltage.


Note that the two curves cross over, but the point where the temperature curves cross is when V GS is at a current of over 40A and the gate-source voltage is 5.

Any suggestions on where datasueet error could be located? The spec is given below, also I have some doubts regarding the project. This application note also mentions the possibility of a failure mode similar to second breakdown when operating switching MOSFETs as linear amplifiers. The network comprising of capacitor C3 and resistor R19 improves high frequency stability and prevents the chance of oscillation.

Also note the capacitor in parallel with R7. Please check and correct and proceed as above. Requests for component values will not be datashedt. Normalising simply means that everything is taken back to a reference of unity, so simply multiply the claimed V th by the figure datasheeh along the left side, for the temperature at which your device will operate.

Finding the correct design parameters becomes more complex with non-linear devices.

It is claimed to be ‘insignificant’, and for switching applications this is true. Rather than increasing the safety margin, the larger device is daatsheet likely to fail if it is working well below the ‘inflection’ current in a linear circuit.

The value for Datasheeh will depend on the linearity of the driver transistors. An example would work nicely here Adjusting the bias to 1 amp removes nearly all distortion, yet now we are approaching a heater Thanks for the help.

I use a k pot but when i turn it off i stil have sound in my speakers, a 1M ohm pot would be good or even it will be small? They exist, but are probably considered ‘exotic’ by most suppliers. This is a minefield, and I suggest that you tread very carefully. Hi, I have one question. Im also planing to do a LED spectrum analyser and digital volume controls with remote.

We want to measure what the load is doing, not what it should be doing. Hello, both my transistor burned out in 2 secounds Q8 and Q7what can cause this problem? The exact values around the Vbe multiplier also known as a bias servo are critical to ensure that the thermal performance is matched as closely as possible. datashet

If u have ideas about these please share. If I power up six of these with the same power supply, what value should each rectifier diode have?

Am I missing something or should the measurement be across just 1 x 0. I hope this short article with aid others in using these ‘switching’ and ‘not linear enough for audio’ dataeheet to get distortion figures below many good irfp92400 with ‘very linear’ devices. Please help me sir.

Well, that is the easy route to take for designing an output stage. It will be great if I get your valuable suggetions.

Why not use a single capacitor?

Using just a pot as shown in P is absolutely forbidden with vertical FETs – a matched bias servo thermally coupled datashert the MOSFET heatsink is essential to prevent both thermal runaway and crossover distortion. I need your help…. It will be noted that there are no component values supplied – this iffp9240 quite deliberate, and is not an omission.

Remember that in 4 ohms one pair can Play up to watts!! You may also like: After fixing the problem by adding a class AB driver, distortion was greatly decreased That is why we need to buy a few extra and match them together.
