The chip I'm going to be talking about is the MCP34063. I really like the chip because it is very cheap, which is great for learning because you will most likely burn some up, and it's one of the older regulator IC's out there so there is some information floating around the internet that can help you get started. I went with TI for this because they have great customer support via their forums which is really one of the best resources out there if you are interested in learning some valuable lessons in design etc... The DIP package is also really nice and as you may have found out by looking at higher frequency switching IC's, not everyone produces a DIP package.
This is a regulator that boosts an input voltage range of 0.9V to 1.7V up to 3.3V. It's based on the MCP1640 which is a 500kHz switching regulator. This boost module can supply up to 100mA. It is up for sale on the products page and is a great development tool!
This is just a quick post going over some basic IO functionality utilizing a booster pack I designed for the launch pad. I am toggling all of the IO pins of interest for my booster pack to make sure this new board I built up works correctly. I decided to post this because it is simple and easy to understand. There is also code for interrupt service routines that may help a few of you out.
