TDA8571J even in the car stereo 200w … 300w sold as cheap car amplifiers used in advanced integrated amplifier operating voltage of 6 volts DC …. 18volt dc circuit is established with very few passive components.
TDA8571J 4×40 W BTL quad car radio power amplifier
The TDA8571J is a integrated class-B output amplifier contained in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in a BTL configuration, each with a gain of 34 dB. The output power is 4×40 Watt (EIAJ) into a 4 W load. Electrostatic discharge protection Load dump protection Thermally protected
Note: If the circuit is fully regulated power supply or smps (pc atx etc.) If you will be running with the + 12v line connected you can use instead of 1 piece 8 2200uf capacitor

Switch Mode Power Supply Transformer Winding
What should lie so fast an intermediate transformer wound in our country SMPS 10 chinese necessary for the production of the song, I thought you might trafor .. almost all the countries of China SMPS, buy an adapter, even assuming that this rate is considered low by them 🙂
