The on resistance is not the same. This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey. Why are newbies always great in ignoring posts they don’t understand it I guess that something’s wrecked the rail.

IRFZ44N N-Channel FET

Carry on, while I go over here and hide. To answer the original question: Not nice and too much strain on your power supply. Home Questions Tags Users Unanswered.

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. Two things to note: And the fet is not a logic level fet, so can’t be driven with 5volt logic. 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.

If not, is there a transistor that allows me to hookup the LEDs in a similar fashion? Like an Arduino pin, it has no current limiting. So why is that sir? And you do remember how well they worked, right?

Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition. That chip if for direct driving small LEDs sink only. A PCA breakout board Adafruit or ebay could do what you want. Wawa on Aug 14, Obviously the upper units cooked because they got hot.

Or do you know for certain what those values are?

Mark Jhomel Olimon 11 1 4. Wawa Shannon Member Posts: Because of this you’ll want to add a master MOSFET on the 12v 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. That would encourage people to look at them to help you. You should see pretty much the same performance from the IRZ44Ns.

Ricardo 4, 14 37 Brendan Simpson 1, 3 Use fricking code tags!!!! 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.

It seems you’re using the wrong parts to control LED strips. I suggest finding a better FET, there are literally thousands of them in that package that would do the daatsheet at least krfz44n well as the OEM solution, if not better.

It can directly drive the logic level mosfets for your LED strips. But only mA per output Not important if you use logic fets to drive e. Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation?

Don’t datasheey about their difference in power. NEW Library to make fading leds a piece of cake https: But I agree the PCA would make more sens here. That is to say, they may well cook too.

Thank you for your answer. The chip can indeed sink more current than it can source.
