can someone sent me a 12v dc to 15v dc converter circuit diagram using mc34063a

hi,

find the attached file,it is shown for 28V output, i got it from the datasheet. Change the R1 and R2 values using the formula Vout=1.25(1+R1/R2) to get 5V

thank you with the circuit, so it means i have to change only R1 and R2 and others remain the same. Is the any order of changing R1 and R2, or is just any order that suits my V out =15v.

Just changing R1, R2 alone is not enough. All components should be selected to suit your needs. Better start with design tool given my manufacturer.
