Split Power Supply Circuit for Power Amplifier

Posted on Feb 6, 2014

This is the very simple circuit diagram of 150W power amplifier. The circuit is easy enough to built without PCB. The power output range is about 100-150W depends to the power supply and the Darlington`s you use for the amplifier. Heatsink is a must since the final transistor is going to hot when the amplifier. This is a Hi-Fi power amplifier cir

cuit build based on single power amplifier IC TDA2040. The single TDA2040 has able to deliver 20W power output. The bridge amplifier which consist of double TDA2040 can deliver 30W power output (8 ohm loudspeaker). About power amplifier IC TDA2040: The TDA2040 is a monolithic integrated circuit in Pentawatt. If you want to create an amplifier that is able to produce a good sound output with low distortion audio, then this amplifier could be the right option for you. This circuit using power supply split type with a maximum input voltage of 25V. Heatsink should be installed on the power IC to avoid excessive. Here is a Hi-Fi power amplifier circuit, built with a power IC TDA2050. This circuit will produce a power output up to 32watt. With good sound quality, high power and very low distortion feature, this circuit will be very suitable for simple and cheap audio systems. TDA2050 Amplifier Schematic diagram: TDA2050 Amplifier PCB Design: About. This 400W power amplifier circuit often called as "safari" amplifier. The 400W power amplifier built using two couples of power transistors that are TIP31 with TIP32 and 2N3055 with MJ2955. These transistors are well known and widely used for the amplifier circuit and power supply circuit. Take a note that you must use aluminium heatsink. This is a very high 1500W power amplifier circuit diagram by Rod Elliott. The circuit is built using 10 pairs of power transistor MJ15024 and MJ15025...
