I've been working on an LED toy for a while now, using a WS2801 strip getting me 48 pixels. I am using around 350-400mA at 5V including powering the Teensy 3. My power is a couple of li-ion 10440 cells in parallel, so 3.7V, around 1200mAh. The 5V comes out of one of these boost converters: https://www.sparkfun.com/products/10255
I opted for that one as I needed something really small and it could deliver the amount I needed. Now I want to start using a WS2811 strip, to double my pixel count to 96. Obviously I'm going to be drawing more power, around 700-800mAh.
So I'm looking for a boost converter that is a little more powerful, but hopefully not much bigger. I've been googling like mad but can't find anything useful that I can buy off the shelf. Any ideas here for what would be a solution? I've looked at building my own circuit, but every which way I try I'll never get it as small as those factory made SMD boards.
