Amplifier circuit for portable speaker project

The ebay ad for the TDA2050 amplifier says DC 12-24V 5W-120W but the datasheet says with a 12V supply the power is about 2W into a 4 ohm or 8 ohm load and with a 24V supply the power is 7W into 8 ohms or 20W into 4 ohms. The 8 ohm graph stops at 22V and 25W. the 4 ohm graph stops at 44V and 40W. The heatsink is too small for power more than 7W.

6 FAQs about [Portable amplifier power supply usage]

What is a good power supply for a hifi amplifier?

So ultimately, the primary characteristic needed is stability, all things considered, the power supply should have no effect on the amplified audio by way of fluctuations in DC potential available to the amplifier circuitry. Practical power supplies for HiFi amplifiers could be linear, switch mode or (less practically) batteries.

Where can I find a good article on amp power supply?

TNT-Audio has a very good article on amp power supply that describes various designs. IT explains the purpose of RC network and small value caps as well as purpose of dual rectifiers. The diagram you show correspond to fig 4/diagram 4 in the article.

Are there any portable amps with internal rechargeable batteries?

From my research, there are limited options for portable amps with built-in rechargeable batteries, such as the Roland Cube, Hog 30, and PJ Briefcase. The only other options I found were complicated conversions from DC-power sources like car and marine batteries.

Do I need a battery powered amp?

There are times, especially when playing outdoor, when there is no AC power available. For those times it would be nice to have a battery powered amp, or a DC to AC converter you can connect to a 12 volt battery. Battery powered amps seem to always have very low wattage output, with small speakers and don't sound very good.

How does a hifi amplifier work?

Audio, Audio, Audio! In any well designed HiFi amplifier, there will be a power supply whose job is to convert the AC mains supply voltage to a DC voltage. The power supply must also be able to provide a reserve of power to cope with any sharp transients in current demand without suffering a decrease in voltage output.

How to supply a band with AC power from a battery?

To supply a band with AC power from a battery would need a battery the size of a truck. Far easier would be a Gas/Petrol generator. Remember it's isn't just the bass amp and PA but all members of the bands amplification equipment.
