Australian supercapacitor manufacturer Cap-XX announced its BriteFlash power architecture to provide LED flash camera phones.
BriteFlash architecture provides enough flash power to eliminate both dark and blurry photos using high-capacitance (0.4 to 1 farad), low equivalent-series-resistance (less than 100 milliohms), thin (1 to 3 millimeters) prismatic supercapacitors to support a battery and deliver the pulse power to drive an LED to full light intensity.
The CAP-XX BriteFlash power architecture is similar to a Xenon flash solution used in digital cameras today, where a low-current charge pump (boost converter) charges the supercapacitor to 5.5 volts then the supercapacitor drives the LED at very high current for the flash pulse.
