The NCP5680 supercapacitor-optimized LED flash driver is offered as the first of its kind to deliver up to 10 A for photo flash and video light in ultraslim camera phones and compact digital cameras. The company claims that this total LED flash solution supplies comparable light energy to xenon flash, but with only half of the comparable solution height (0.55 mm) and no need for an extra LED for video capture. Today’s WLEDs can deliver this level of light energy, but require up to 400% more power than a camera battery can provide.

There is mention of a development board too.
