This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...
The circuit was designed to produce high quality and powerful audio amplifier that would provide 60W-90W power output. MPSA43 – NPN high voltage transistor with low current and high voltage used for ...
The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
