I have a new project hitting the drawing baord!
I have begun work on a super efficient led power board for a flashlight. I will have two designs. One for use with a single li-ion cell and one for use with two. The reason that two designs are needed is with only one cell I will need a boost converter while with two cells I only need a buck converter.
Why not just use a buck-boost design? The problem with a buck-boost when compared to a standalone buck or boost is the efficiency. With modern inductor driven DC-DC converters a efficiency greater than 90% can be achieved which is critical in high drain battery powered devices.
Goals for these modules are as follows:
-High efficiency
-High reliability
-Low cost per unit
-Micro controlled with multiple power settings
-Possible firmware update methods
-Built in battery protection enabling the use of non protected li-ion cells for higher capacities
As always if you have any ideas or suggestions for this project just let me know.
