The Max1880 is a DC-DC converter. The Maxim IC you want is a either a Max6657 or Max6658. Micrel makes a similiar part, a Mic280.
Your best bet is to contact Maxim direct.
Here is a link. They will sell in low quantities, unlike some manufacturers. The online stores I know of that carry their parts don't carry those particular parts.
