Buck drivers, like linear, need more voltage than diode requires. However, there is one HUGE advantage. While linear drivers convert unused voltage into heat, buck drivers can actually convert it into more current. Example: 0.4A 8.4V (two fully charged 10440's) in, 0.6A 4.5V out (including efficiency loses). 12x from dual 10440's - not bad! I was looking at buck IC's and some seemed pretty cheap and usable. Would anyone be interested in getting such drivers, if they costed around $12?
