DIY Class D Audio Amplifier:
DIY Class d Audio Amplifier circuit diagram. this is a circuit diagram. It can make 300 watts using 50-0-50 voltage. this type of circuit needs mosfet. positive mosfet and negative mosfet. here positive mosfet is irf9540 and negative mosfet is irf540. it’s a mono-circuit diagram.
The designator is IRF9540N. the type of transistor is MOSFET. type of Control Channel is a Positive Channel. the maximum Power Dissipation is 140 Watts. the maximum Drain-Source Voltage is 100 Voltage. the maximum Gate-Source Voltage is 20 Voltage. the maximum Gate-Threshold Voltage is 4 Voltage. The maximum Drain Current is 23 Amperes. The maximum Junction Temperature: is 175 °C. the total Gate Charge is 97(max) nC.
This is the diagram
Please use strong voltage. Always use the best quality transformer diode and capacitor to produce good voltage. here needs a minimum 2200uf and 50 voltage capacitor. the diode will be a minimum of 6 amperes. This board doesn’t have any output protection system. so needs speaker protection to protect the speaker. if the IC gets a short circuit then the protection circuit will protect the speaker from being burnt. the protection circuit diagram

This circuit needs a heatsink for the MOSFET. because the MOSFET makes it hot when it runs. Please use strong voltage. Always use the best quality transformer diode and capacitor to produce good voltage. here needs a minimum 2200uf and 50 voltage capacitor. the diode will be a minimum of 6 amperes. This board doesn’t have any output protection system. so needs speaker protection to protect the speaker.
