Hi, i will be Much Much Obliged if someone can Help me, i am Really Sucked up Using IR2110, as i don't know any other available msft Driver in market here,
Issue
1) Main issue Bootstrap doent start working when The Vcc is below 21 Volts, i.e High Side start working When the Vcc is Greater than 21 Volts :'( Bootstrap Diode tested 1n5819, Byv26, Byv27, Fr107, FR106, FuF106, 1n4007, Tested many Boot capacitors too
2) The output at Ho is not Pure square wave it has slop at top, and its not straight line
There is some noise present also
i used ferrite beeds(b/w driver and Mos Gate) to remove noise there is lot of improvement but not completely removed
Waveform pics are Attached please help me if u anyone can
