I need to go from 7.2v lithium battery pack and provide 3.3v to an application. i need something very efficient. Maybe a Buck Voltage Regulator? Has anyone any experience with these? I looked them up on digikey and the support circuitry looks intense. Caps diodes and an inductor? Wow, any experts ot there on this?

Go to the National Semiconductor website http://www.national.com/appinfo/power/switcher.html (http://<u>http://www.national.com/appinfo/power/switcher.html</u>). They have a line of SMPS controllers called "Simple Switchers" and an online parametric calculator to help you select the few additional discretes required for your app.
