3.3V to 30V DC/DC converter using SN6505A

Bob tipped us with his latest project. It's a 3V3/30V DC/DC converter using SN6505A from TI. Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input...
