i am currently working on a project of making a portable battery charger for mobile phones.
firstly, i started with lm7805 regulator but it consumes a lot of power, then,
there is a solution with linear technology lt1302 ic but i don't have this type of ic in my area.
so i used a simple step up converter from 3.7 to 5v ic mc34063 for providing 5v and 1.5A current , i wanted to know if the calculations i made for the components required are feasible and economical.
i am attaching a photo with this to show the circuit with calculated values.
thanks in advance.
