Hi Stewin:

I used IRF630 in power board hope this is okay as other version used 10N20!

Is the any issue if I use 10uF 16v capacitors?

Thanks
Raj

Just don't remove my name when you etch the PCB. It gives me the credit for my effort.

Happy new year everyone
thanks jlister for sharing . but in the schema like the original ir900d you can't use +/- 65vlts or above comfortably . pls change the cd4049 stage to use three inverter buffer stage like irs1500 or aud ver 1 and 1.1 amps

Hi Raj,

Near IR2110 use 10uF/63v(for low voltage Max.55V) or 1uF/100V(for Max.90V)

all other which you specified can use 16v range.

Regards
MANOJ

Hi Manoj:

I would like to buy some IRS2092, high power MOSFET, inductors. Can you please let me know where in India I can buy them, Culcatta/Banglaore preferred.

Or any online shop in India to check price and availability.

Thanks
Raj
