Hi everyone!
I have made a class D amplifier circuit using IRS2092 driver. I have used IRAUDAMP7S design as reference. I have chosen IPP320N20N3 MOSFET.
After many attempts, my amplifier doesn't work.
The fault LED blinks 2 times every second
When I turn off the power supply and the supply voltage is ±50V, there is no more fault.
I have tried many deadtime and current limit.
My power supply voltage is ±70V.
My speaker impedance is 8ohm.
Thank you
