100W Power Amplifier TIP142/TIP147

Today I will share a power amplifier circuit entitled 100W Power Amplifier TIP142 / TIP147. Power Amplifier is so powerful, with 100Watt RMS power output at 8Ohm impedance, and has 150Watt RMS power output at 4Ohm impedance. The power amplifier circuit is capable of lifting 12Inch speakers with 200Watt 8Ohm power, both used for mid, midbass and subwoofer.

Below the Circuit Diagram and PCB Layout Design:
100W Power Amplifier TIP142/TIP147
In the scheme, the final transistor used TIP142 / TIP147, for the transistor datasheet you can find at datasheet file-base. The transistor has an NPN / PNP Darlington construction, so it has a stronger reinforcement. For buffer and driver circuit I use Transistor BC556AP PNP Transistor and TIP41 NPN transistor. For the installation of the driver transistor (TIP41) it is recommended to install the cooler with the final transistor, this works also for Thermo switch.

Power Supply Voltage required minimum 25V DC - 45V DC, To achieve good sound, use a well-filtered power supply circuit and use a transformer with a low amperage of 5A. Power Supply Such as this: Power Supply Circuit for Audio Amplifier

Led Lights on Music using LB1403 and transistor

On this occasion, I will share electronic circuit schematics on how to create the Led lights in conjunction with the music, or lights flashing on the music. This circuit is quite simple, the circuit has also been widely spread on the internet. However, at this time I will use a lot of lights to turn the lights on music together. By using audio signal amplifier circuit which will be forwarded to led using IC LB1403. However, I added a PNP transistor again to amplify the voltage going into the LED. So the Led used can be much lighter and more stable.

Immediately PCB without the following scheme, or you can buy PCB here PCB VU LED LB1403:

PCB LB1403 Circuit
On the PCB above that is so then slightly modified for the placement of the led lamp driver transistor, so I added a hole and removed the 330 Ohm part to directly connect it.

Led Lights music circuit
I removed 330Ohm Resistor, and jumper it. Because of the + Voltage for supply the emitter PNP Transistor TIP42. So that required 12V Voltage.

Transistor TIP42 Datasheet
Above is a PNP transistor, the transistor I use is TIP42C type with the foot construction as above.

LB1403 Circuit led lights music
Then after the incoming voltage to the transistor emitter is already full, I added a hole for the emitter leg so that the base and emitter can go directly to the PCB.

Led Lights music pcb
My transistor is soldered. into the PCB by bending the foot to be affected by the opening visible copper, so it can be soldered.

TPA3116 Class-D 2.1 Power Amplifier (2*50W + 1*100W Subwoofer)

Recently I was bought TPA3116 Class-D Digital Audio Amplifier on Online shop, that price about $12USD. This TPA3116 Power Amplifier has 2.1 channel output that has 2 midrange output speakers and 1 output for subwoofer speaker. In the mid output or L / R output of each power has 50w, while the subwoofer has a power output of 100W at 4 Ohm impedance. Below the description or wiring connection of TPA3116 2.1 Class D Amplifier:

TPA3116 Class D 2.1 Power Amplifier 50W + 50W + 100W Output Power
About this Amazing Digital Amplifier Class-D TPA3116 2.1 Channel:

The amplifier board adopts two imported TPA3116D2 digital amplifier chip as the core,one piece as left and right channel power amplifier,other piece as pre-bridge briver with NE5532 subwoofer ,with a small ,high effeciency,high power characteristics.

Product name:2.1-channel audio amplifier
Chip Select:TPA3116D2
Supply voltage:DC 12-24V
Output power:50Wx2+100W Subwooferx1
Output Impedance:4-8ohm
Frequency range:14-100Khz
Number of channels:3(left channel,right channel,subwoofer)
Switch frequency:1.2MHz

For the use of power supply, this power amplifier does not require so large working voltage. You can use 12VDC voltage to work on the TPA3116 power amplifier. However, to use a power amplifier with a maximum power, I recommend using a maximum voltage of 24VDC. In this project, I'm using 12VDC Switching Power Supply with current 8 Amperage.

TPA3116 and 12V DC Switching Power Supply

In this experiment, I tested power amplifier using 12 Inch subwoofer speaker with 200W 4 Ohm impedance for the subwoofer channel. And 2 x Midrange 3.5 inch along with tweeters. Here's a picture of its speakers and video test.
