che-900e is not working ir2110 ic get hot i think ic voltage com to Vdd is 5v but this schementic is give 12v

the irs3000d dint gave up signal out from 2n5401 and the other one just blew the **** out from IR2110....cause me to lose 5 of it in a time......the frequency was a good square wave from 2n5401 in other design...but no respose from 3000d.....inspite of the frequency on the outputs there was no response from IR.....the low output of IR gave out square wave signal but the low side was still showing something and that something was a freaking "NOTHING"
i tested these designs with +/-30volts

sweet perfume you are very unlucky or maybe your ir2110 chip is bad or the aux voltage feeding the ir2110 has not reached 12vlts. happy independence day to all too.
i dint install IR2110 yet i was checking the things up that ie there everything ok...but i dont think that something ove there was ok
Traces are long,ground plane is missing,ground is not thick enough,you will have problems in high curents, but it should work ok for a few wats,if it blew form the start then you made some mistake🙁..

"the 5401 gave the clean square wave output"
What do you mean by that? one transistor alone can not give any output..

What amplifier are you making???..you will have NO wave forms without all the parts installed and working corectly since all the amplifiers on this thread are self oscillatting ones.
i built one of the ir2110 model but it had lot of distortion...then i got the pcb design from thienchay of irs2000d/3000d which i tried to see whether works or not...can u tell me does that work well...and what will happen if i install all the things except output fets..to see whether the IR2110 gives the high and low output correctly??????????
wire resistor
Is there any possibility that you have used wire resistor,you might have and the have inductance so use carbon ones...just a thought...

time recent i'm so busy , so i not yet try this PCB .
I'm temporary check , and i see R 4K7 and 1K is wrong , Detex is deceit , and i see C 100uF is not a bypass Capacitor , it connect from Ouput of TL071 to -5V6 😕 , try swap 4K7 - 1K , and remove C 100uF .
And i 'll check it soon to find a good sch and PCB , some mistake from me , sorry .
Regards .
