Thanks srnet. Cheap isn't critical, I'm willing to pay extra to make it work right. I just thought the $23 per IC that the data sheet calls out is steep. Also, as mentioned, they're no good anyways as they are only step down regs.
Hi Tom,
It is a 12V battery, Samsung INR18650-15M battery pack... 3 cells to make 12V. It is basically a Milwaukee tools M12 battery pack.
