Class D Amp meets SMPS - the TPA3255 300W x 2 meets 600 Watt SMPS

In this video 'Class D Amp meets SMPS - the TPA3255 300W x 2 meets 600 Watt SMPS', I'll showw the noise from the SMPS and how it shows matched with the Class D 300Watt x 2 Power Amplifier. The Class D amplifier is powered by the Texas Instruments TPA3255 Power Amplifier. This is a video to see if the Switch Mode Power Supply is acceptable to power an Audio Amplifier. #TPA3255 #ClassDamplifier

Sir you spent so much time to edit video I watch your audio based videos
One one thing please add adaptive noise reduction in your video for no noise clear audio

[BogdanSerban]

It's a two switch forward topology and the small transformer is a gate drive transformer (you can see the traces going to the transistors and the two reset diodes).

Hello, I plan to buy an ACEIRMC 200W Pure Bass Subwoofer Crossover Second-Order Crossover Frequency Distributor Divider 2 Way Speaker Audio Crossover Filter

to combine it with an Aiyima A3001 TPA3255 sub amplifier that has a frequency filter but together with this it would surely give a spectacular pure bass?

Hi Eddie, thanks again for this great video.

[fuchoi]

ya, we expect to something like 65dB PSRR on chip Class D amp. Really interested to see the noise performance of the SMPS using dynamic load and how we measure it. Also, how it affect the output performance of the Class D amp.

Got a question.can you bridge the output of this amp board? I'm looking to set up a dual monoblock configurations.

1:23. Good timing BTW.
I hate to say it but, if you would have gave “Specifics” abut the state of the world, this platform would have throttled this a little more than usual.
I say that to say this. 👍 “watching you share your knowledge, is a stress reliever for me, at times like this” .
God Bless.

Dear Eddie, thank you for the review.

Could you please share your oppinion on the possibility of replacing the two 4700 mkF power capacitors with a pair of 10000 mkF ones, while the power supply is a switching type 48V 7A -- will it affect the TPA chip's operability? What will be the overall effect, if any, of such a replacement? Thank you in advance for your oppinion.

I also invite all other people in the know to express their views on this idea.

I've got a board with 2 chips in PBTL mode and 2 *real* nVidia fans! It all usually works well, until the 1uF Caps at the output blow up.. any suggestions on how to fix this?

[Chupacabras]

Nice video. Very practical. I like it.

[josue]

hello, I don't understand your video, I only know Spanish, I'm using the translator, I wanted to know what the real power is without distortion and how much impedance was measured

[sunuk]

It's great video series 👍 👏 👌
Thank you very much for clear explanation

Can i use 36V 500watts power supply for this amp?

[nsqtr]

Into a 4 OHM load how many watts tpa3255 can provide without clipping ?

[nigelpearson]

For fun I made a junk box psu for a cheap class D module I had. The most primitive filter worked best. Low value resistor ( 0R33 ? ) and 10 000 uF. Sometimes this will trip the smps current limiter, not this time. Place the filter close to the amp. The results were just what I wanted with much better RF noise. 50 Hz area also. A linear supply not really better. I prefered the smps using ears. More solid in the bass. A scope was used. 80% of the time an idea like this doesn't work, too simple. I suspect the 10 000 uF was just about OK at 65 kHz. The amp is decoupled and uses 240 kHz with no output filter. Out of phase bridge with class D switching in phase. In theory the speaker will not see the 240 kHz. I got rid of the 65kHz.

[paulcottingham]

We need a GaN switcher without the noisy fan for audio.

[rajendrabareto]

How much watts it can give with 36V and 15 amps smps

[johnshaw]

Being as class D is itself a type of switching PSU, does the powering PSU quality even matter?

[amplidude]

Couldn't you do a video on a diy emp bomb for my friendly neighbour's in the east

[eliseoquiroz]

I need the next video Eddie 🥲. I'm looking forward to this series with TPA3255 amp. I want to make a 4 channel amp and mono amp using this chip.
