6 18 Volt audio power amplifier

This time I will post about the audio amplifier based on IC KA2204. In an audio amplifier circuit has a power output that can also be referred to as a low-grade resources that have only 6 Watts output with 4 Ohm impedance. Frequency response 30 Hz to 18 kHz . For the scheme can be seen below.

Supply voltage and a maximum of at least 6 Volt to 18 Volt

Part List

R1 = 56R
C1 = 1uF
C2 = 220uF
C3 = 100uF
C4 = 47uF
C5 = 1000uF
C6 = 100nF
C7 = 470pF

C8 = 22pF

C9 = 47uF
C10 = 47pF

6 to 12 Volt Power Supply Inverter

This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car.
The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages.

6 Watt stereo power amplifier schematic

Basiccally,this amplifier works with the IC, which is where ic is associated with several other components in the supply and use DC voltage, which corresponds to the needs of IC above course on the circuit schematic. For IC , stands intregated circuit used is ic LM379 which has a maximum 6 Watt stereo output. This IC manufactered by NS and with SDIP-14 package. While other components needed in the circuit schematic , you can see components of the list below.

Component List :

6 to 12 Volt Converter

Below its a converter circuit voltage from 6 Volt to 12 Volt DC.

6 Volt to 12 Volt DC

Part List :
R1, R4 2 .2K 1/4W Resistor
R2, R3 4.7K 1/4W Resistor
R5 1K 1/4W Resistor
R6 1.5K 1/4W Resistor
R7 33K 1/4W Resistor
R8 10K 1/4W Resistor
C1,C2 0.1uF Ceramic Disc Capacitor
C3 470uF 25V Electrolytic Capcitor
D1 1N914 Diode
D2 1N4004 Diode
D3 12V 400mW Zener Diode
Q1, Q2, Q4 BC547 NPN Transistor
Q3 BD679 NPN Transistor
L1 See Notes
Notes
1. L1 is a custom inductor wound with about 80 turns of 0.5mm magnet wire around a toroidal core with a 40mm outside diameter.

2. Different values of D3 can be used to get different output voltages from about 0.6V to around 30V. Note that at higher voltages the circuit might not perform as well and may not produce as much current. You may also need to use a larger C3 for higher voltages and/or higher currents.

3. You can use a larger value for C3 to provide better filtering.

4. The circuit will require about 2A from the 6V supply to provide the full 800mA at 12V.

Faster Battery Charger Circuit 6 12 Volt with IC LM308 and LM317

This circuit is quickly charging the battery . If you need a faster charger ,this circuit is recomended to you . And this charger is low temperature , the temperatur is 5 degree celcius. Input Voltage is 15 Volt DC , and Output voltage to charging 6 -12V and you can adjust by the D1 (see schematic). And adjust the D1 to 50 mV greater VZ than D2 (see schematic). Couple the D2 to battery. This circuit operating by IC LM308 and LM317 and any other components. And you can use this circuit to charging Accu 6 or 12 Volt , dry or wet and other battery .

See this Schematic Circuit below :
