On this occasion I will share a very good and simple D-class power amplifier scheme with 900W RMS power, this scheme I design in Easyeda. This scheme originally is made by Mr.Kartino Surodipo. This D900 new design have 2 features that is New Feedback design and Input Comparator. here is the power amplifier scheme:

I design the pcb layout using the SMD component, and you can see the component list via .xls file download here: BoM CLASS-D Power Amplifier D900 IR2110 - SMD
Recommended Power Supply that using for this class-d amplifier: 50VDC - 90VDC with current minimum 10A.
