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

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....

Add an auxiliary voltage to a buck regulator - 31-Oct-02 Issue of EDN
You often needthan one regulated output voltage in a system. A frequently used and
reasonably simple way to create this auxiliary output voltage is to add a second
winding to the output inductor, creating a coupled inductor or a transformer, followed
by a diode to rectify (peak-detect] this output voltage.... [Design Idea by John
