1.5V battery powers white-LED driver

Although white LEDs are common in a variety of lighting applications, their 3 to 4 V forward-voltage drop makes low-voltage applications challenging. Charge pumps and other ICs are available for driving white LEDs, but they generally don't work with the low supply voltage of 1.5 V in...
