I am very interested in the IP5109, but don't feel like making my own PCB around this chip :phew:
Do you know of any powerbank that would use this chip (as the Miller ML-106 with the IP5108) ?

I'd like to test this IP5109 board and use chunks of this :


here :


and there :


What do you think ?
Where can I purchase one ?
crazyguy:
use a large heat sink will increase the size of the powerbank

I don't think you can purchase this demo board anywhere, send a email to the IC company maybe they would be kind enough to give you a copy for testing

Well it's not so large, the width is only 14mm (0.55 inch) and the height 6mm (0.23 inch) !
And I was thinking I could trim its length according to the hot surfaces it has to be glued on on each side of the PCB ...

That's what I'll do.
Is Changdiantou a distributor only or the original IC company ?
Apparently, their website is about video rentals ... ?!?
