I am designing a Class D audio amplifier and using IR2104 to drive the two N-Channel MOSFETs IRF3205.
I have enclosed my circuit in the attachement. The output at Ho and Lo pin is not high enough to drive the gate of the mosfets. The value at these Ho and Lo pins are in mV. Any suggestion for the circuit?
I have to design the circuit for audio input but as of now I am using a 1kHz sine wave as audio input and 5KHz triangular wave to create 5KHz PWM wave which I am giving input to 'IN' pin of IR2104.
