10µA Quiescent Current Step-Down Regulators Extend Standby Time in Handheld Products -  DN235  Design Notes (Linear Technology) (App Note - added 1/06)
2 AA cells power step-down regulator -  01/07/99 Issue of EDN  DC/DC conversion is particularly challenging when both the input and output voltages are low. Step-up ICs that operate with inputs lower than 1V are available, but step-down ICs that accept input voltages....Page includes several designs.  Scroll to find this one.... [Design Idea by Len Sherman, Maxim Integrated Products, Sunnyvale, CA]
3.3V converter delivers 3W from Li-ion battery -  11/05/98 EDN-Design Ideas....Lithium-ion batteries are rapidly gaining popularity in portable applications because of their superior energy density, low self-discharge rate, and high cell voltage. When you use one Li-ion battery to power a 3.3V dc/dc converter; however, you encounter a problem, because the battery voltage….Several circuits here, scroll to find this one....
