Class D with integral SMPS

[e_fortier]

Hi

I’m looking out of pure curiosity at amplifier with integrated power supply. Looking for a minimum of 50w into 4 ohm per channel.

What are our choices for DIYer besides the nice sounding units from IcePower and Hypex Ncore ? I already own an amp from both these manufacturers, I enjoy them a lot but want to know what else is available and good sounding.

My reasoning is that when the supply is incorporated into the same pcb as the amps the following was hopefully done properly on the SMPS ; sizing, protection (voltage, current, temperature), pumping effect to just name a few.

Price wise I’d like to pay similar price as IcePower stuff.

Thanks for any recommendations

Hi


i personally do not know this board. but i noted after reading a thread about tpa3116...i remember this:


HIFI TPA3116 2.0 Channel Digital Power Amplifier Board Switc Power Supply Amplifier Board 2*60W AC 100 240V -in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group


sorry its not the level as the ice but worse a try?

I recently saw someone sharing exactly that type of circuit.
AMPSMPS TPA3116 + SMPS - EasyEDA

So I guess a couple of people took the change of putting the design onto an PCB and sell it.

Thanks for the replies.

Anything else out there for us to have fun with ?

Hypex have some small multi-channel 30W units, the UcD3xMP series.

The 2-channel one is out of stock and not made any more.
The 4-channel one is out of production, and they're selling the remaining stock cheap.
The 6-channel version is aparently still made.

Anaview has several variants from 2x50W up to 1x1000W. Linking to Strassacker, since Anaviews own site is down for maintenance.

Anaview site has been "down for maintenance" for a while now.
Are they still in business making amplifiers?

Hi Chris

I finally bought an IcePower 125asx2 and really enjoy the sound.

I never enjoyed the TPA...stuff but thanks for the suggestion.
