Use supercapacitors to drive a white LED camera flash Design How-To 5/13/2005 Post a comment LED photoflash solutions using supercapacitors, with combined high capacitance (1F or more), and low ESR (< 100milli-ohms), provide the pulse power required by the LED without taxing the battery. A Cap-XX applications engineer offers two complete designs for camera phones. One solution places supercapacitor at the output of a buck-boost converter; another solution uses a supercapacitor in series with the battery. From the May issue of Planet Analog magazine, here's the complete design analysis.
