Switching circuit for a power supply

[BRetonDP]

Hello, EEVBlog community!

I am currently building a very cheap power supply which I want to have backed up by a 5V power bank.
I was going to use an integrated circuit that did the switching for me, and I found the LTC4412, which is exactly what I'm looking for but in a very inconvenient package (I am using DIP and that comes in TSOP-23, which is way too small). The datasheet of the IC can be found here.

I'm only going to be handling 5 volts. Do any of you know of another integrated circuit (or a circuit I can build) which does approximately the same and comes in an easier to handle package? Thanks in advance!

Hey, evb149. Thanks for your reply. The currents I will handle are well below 1A, so I think it wouldn't hurt me to try the diodes.

And true, the packaging isn't so bad, but I'd rather work with something else; I don't really want to risk damaging the IC by accidentally burning a pin off or something.
