Tool/software:
1. Why analog and power ground both needed simultaneously? how can we use them in our circuit?
2.Why the NC PIN(PIN11) is connected to a resistor and then grounded?
3.What is the range of input voltage required and input current required?
4.Can we change the switching frequency? if yes then how?
5.why the specific values only chosen for resistors and capacitors?
6. What is the need of 2 parallel capacitors at input side?
