The 2 channel 400w class amplifier circuit consists of the NE555 timer, the preamplifier based on LM393 opams, the PWM module ( LM319, THS4271 ) and the ir2110 MOSFETdriver circuit sections, which are combined into separate modules. IR2110 Mosfet, Power supply single working voltage of 65v dc. 800w Class D amplifier project previously shared Class D amplifier having a somewhat complicated design according to the circuit, but the circuit of the landmarks of the calculation formulas ( Class D output filter, power calculations, PWM, etc. ) administration of different does of the source eagle pcb drawing Claas D amplifier projects for It might be useful.
