The application it will be used for is a bike light. 6v 15w bulb, the battery is a 10.8v 3.6 Ah that is doing nothing right now. I figure a burn time of about 2.5 hrs with this if I get it down to 6 volts. Because its on a bike I wanted to keep it small. Also thinking about a digital controller...
Looking to drop a 10v Li-on battery to 6v DC. What is the most efficient way without to much wasted power. Adjustable voltage regulator? diodes?,
something else? needs to be small. Thanks
