hi again mr manojtm
can you please share part list of your amp and swichin power?
it is important beacuse i do not know which of resistor are 1% for example and some of part is unknown to me.
very thanks friend

Hi Hadi,

all resistors are 5% except ** one (1K 1%) you can vary the value ex: 1K or 820 Ohm or 680 Ohm or 560 Ohm or 470 Ohm. lower the value will increase the fsw. NB:keep in mind your MOSFET(low switch ON,100nC and high speed switch) will support the high fsw.

LC value also vary when you change the fsw ex: 500 Ohm resistor L&C will be 33uH & 0.47uF/250v (fsw = @400KHz)

IR2110 pin 5 & 6 connected capacitor is 1uF/100V.(type mistake 10u/100v)

and snubber 47 ohm 0.5W with 100pF/1kv,MUR1560 & 25uH coil is an optional ( it is for EMI reducing)

Regards
MANOJ
