hi,
I am doing a project on power supply design. my input is 12v,1amp. my required outputs are 7v,400mA; 3.3v,500mA; 1.8v,600mA
i have a quest..
>what is the role of inductor used in switching regulator?
>how to select the inductor for a particular switching regulator?
>on what factor does the value of inductor depend?
>in linear regulators, is the input current equal to the output current?
>Does the PCB also draws some current after fabricating IC's on it?
>how to calculate the input resistance of the switching regulator IC?
