Simple circuits 1.5 V DC to 9 V DC
I did a brief review of the TL499A, and I believe (from the data sheet) it will do what you need:

There is a DIP package available, and the data sheet gives a pretty complete application example on page 4.  Mouser shows these chips available for $1.50 with plenty of availability.

You should definitely figure out your current requirements as well.  Handy charts are in the data sheet to help you determine if this chip can supply the current you need.
