Not nice and too much strain on your power supply. Here is the question: Wawa Shannon Member Posts: Home Questions Tags Users Unanswered.

It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on. It seems you’re using the wrong parts to control LED strips. Carry on, while I go over here and hide. This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey.

Thank you for your answer. And you do remember how well they worked, right? Dataxheet only mA per output Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition.

Or do you know for certain what those values are? That is to say, they may well cook too. That would encourage people to look at them to help you. Ricardo 4, 14 37 Sir I was an IT student but I want to repair my Amplifier on my own, I knew a lot of things about basic electronics, however, I failed many times in troubleshooting an amplifier.


I guess that something’s wrecked the rail. What I’m trying to say is that unless you know why the original units failed, just replacing them does not address the reason for the failure, and it may well recur.

It can directly drive the logic level mosfets for your LED strips. Wawa on Aug 14, But is will invert the PWM and you might not be able to dim fully to off because the leds will now be on in a blank period.

And the fet is not a logic level fet, so can’t be driven with 5volt logic.

Obviously the upper units cooked because they got hot. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Don’t care about their difference in power. A good LED library can be found here. Unless you can be sure that both transistors jrfz44n way over-spec’d for this application, you must care about the differences between them.

Because of this you’ll want to add a master MOSFET on the irfz44 line that will keep it closed until your contraption is ready for work, because if you don’t, all the strips will turn fully on on startup producing bright white.

Mark Jhomel Olimon 11 1 4. I suggest finding a better FET, there are literally thousands of them in that package that would do the job at least as well as the OEM solution, if not better. iirfz44n

Would you like to answer one of these unanswered questions instead? But I agree the PCA would make more sens here. You can hook up 12V strips directly. So why is that sir? It’s generally not a good idea to under-spec a replacement part, especially if the original failed in the application it was designed for. Use fricking code tags!!!!

I had the wrong datasheet. Can I replace it without major consequences?

The gate threshold is the same, the unit ON-resistance is about the same, and the max currents are about the same. Why are newbies always great in ignoring posts they don’t understand it Brendan Dtasheet 1, 3 The chip can indeed sink more current than it can source.

To answer the original question: If not, is there a transistor that allows me to hookup the LEDs in a similar fashion? That chip if for direct driving small LEDs sink only. The on resistance is not the same. You should see pretty much the same performance from the IRZ44Ns.

Thank you for your interest in this question. Like an Arduino pin, it has no current limiting.
