After searching every shop in the market...I found only one shop with two pieces of IR2121 left... I was very lucky to say the least...anyways...I'm pretty happy that I have one...but I have to say...these driver ICs are certainly expensive.(it costs Rs. 165, which is about 3$) I'll have my circuit ready within a day...will let you know whether it works or not.
BTW...I found that only low side drivers cost more than high and low side drivers. Why is it so? Shouldn't only low side drivers be less complicated?
