I have just found the voltage regulators and DIP form and want to use these for my project. I havent been able to find a 12V output (~15V+ input) module in DIP form with an output capable of at least 2W (preferably more).
Has anyone come across something like this before?
Compared to a linear regulator, a switching regulator is ~85% efficient, meaning it dissipates much less power. However, the inductor and catch diode will take up some space.
On page one it shows an example of a circuit with the switch regulator. What is the minimum I could get away with using to allow it to work, just a single undctor and catch diode, or will I need all the capacitors etc shown.
You ABSOLUTELY need all of the capacitors. The only one you might be able to cheat on is Cin. You still need something, but you might be able to reduce its physical size to the next smaller can.
