The project is due before the end of the month and I am not sure if the logic level mosfet I ordered will be available soon enough. AF modulator in Transmitter what is the A? This is ther difference between the best material and the worst case one.

Daatsheet components can withstand more than their ratings. If you have try other devices you have. The coil in the original schematic is 1mH and I am using a uH one.

IRFZ44N – Infineon Technologies

Yes, that is very good. How can I protect the FET from excessive gate voltage and at the same time drive it efficiently? Haven’t received registration validation E-mail?

If you drive it correctly, there is no problem. I measured the voltage between source and drain but made a mistake when I posted the question. Forum Themes Elegant Mobile.

Manipulating the switching frequency by modifying the hysteresis loop though I dont know whether I should increase or decrease it. I imagine more adjustments should be daatasheet to the circuit when replacing the biploar with the FET. Part and Inventory Search.

With this formula we can easily investigate the power that will have to be dissipated with different levels of drive current. Synthesized tuning, Part 2: You mentioned in your previous post that you can help with the power dissipation in a switching circuit: You can adjust the frequency by changing the 68 pF capacitor in series with the resistor in the opamp’s feedback.

Now that the buck coverter is in place and with ratasheet “right” transistorit works swell!!

Do you have a scope to check a few things, such as frequency, etc? The formula assumes one switch on and one dattasheet off per period not a problem. BTW, the ‘AC was just an example.

It never occured to me that the FET was in danger since a quick glance at its datasheet showed that Ids Max is 49A, and my load should draw only A. After looking at the datssheet for the FET, I think you should use 2 1rfa44n in parallel, and use a heat-sink as well. With the sink I could barely feel a difference compared to room temprature after 2 and 3 minutes of pumping 4A.

Dec 248: BTW, MrCal, your analysis above was excellent. Perhaps someone can look for more info in this area for us. That said, here are a few notes and then the circuit Now, the PIC, even though it’s rated at 25mA, will drop datsaheet more voltage.

I should have picked one with 1V Vgs-th, but I’m now curious: Digital multimeter appears to have measured voltages lower than expected. Tested my setup with a new batch of Z44N’s and they didn’t turn on either, just like the Z46N’s.
