"MSP430 Ultra-Low Power Microcontrollers           
        
Simple 1.5 V Boost Converter for MSP430

A simple, efficient, low-cost, boost converter to take 1.5 V from a single  
type-AA alkaline battery to the operating voltage required by the MSP430  
family of ultralow-power microcontrollers is described. Expected battery  
life is up to 1000 hours.

Of course the MSP430 DC/DC convert does have regulation, unlike the  
ATtiny15 explosive
example.  Convert works with anything, simple transistor based design.
