240/120 VAC household outlet rectification, bucking, and regulation to input 3.3 VDC to MSP430

Hello,

I'm trying to power an MSP430 from a household power outlet (240/120 VAC). I need help finding an AC/DC converter that could take a possibly stepped down AC voltage from the wall, and a DC/DC buck converter that outputs and regulates at 3.3 volts and takes the same DC input as the output of the AC/DC converter. TI has many converters and regulators but I am having difficulty finding the right combination of products that will synchronize with each other.
