Normally when looking for new parts on Maxim's website (or a distributor website) you would first indicate that you're looking for, say, a boost converter and then you'd filter by specification "Well, I have to make sure it can take between 2.5 volts and 5 volts and I need it to give me at least 3 volts output, and I need about 200 milli-amps output."

When you search, use the filtering tools to pare down the large quantities of parts to a half dozen or so. Then you might star some as you're going through them and then look at them in detail later when you want to look at the datasheets in more detail. Star which ones you want, they'll show up in your Favorites!
