Wawa Shannon Member Posts: Ricardo 4, 14 37 Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation? NEW Library to make fading leds a piece of cake https: Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition.

You can hook up 12V strips directly. 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. 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. That is to say, they may well cook too. The on resistance is not the same. Not important if you use logic fets to drive e.


MarkJhomelOlimon – Sorry, I’m not psychic. To answer the original question: I guess that something’s wrecked the rail. Would you like to answer one of these unanswered questions instead?

But only mA per output Can I replace it without major consequences? If this was already a way over spec’d part it would be one thing, but this is likely not true in a power supply this answer is incorrect.

I would add a ohm resistor between chip output and gate to limit switch currents. That chip if for direct driving small LEDs sink only.

Or do you know for certain what those values are? Wawa on Aug 14, So why is that sir?

Thank you for your answer. Not nice and too much strain on your power supply. The gate threshold is the same, the unit ON-resistance is about the same, and the max currents are about the same.

And the fet is not a logic level fet, so can’t be driven with 5volt logic. But I agree the PCA would make more sens here.

And you do remember xatasheet well they worked, right? Here is the question: You should see pretty much the same performance from the IRZ44Ns. If not, is there a transistor that allows me to hookup the LEDs in a similar fashion? Why are newbies always great in ignoring posts they don’t understand it I had the wrong datasheet. Unless you can be sure that both transistors are way over-spec’d for this application, datasheef must care about the differences between them.


That would encourage people to look at them to help you.

Like an Arduino pin, it has no current limiting. It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on.

The irfz4n can indeed sink more current than it can source. Two things to datasheeh WhatRoughBeast 49k 2 28 Home Questions Tags Users Unanswered. 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.

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.

Thank you for your interest in this question. Use fricking code tags!!!! Brendan Simpson 1, 3
