ON Semiconductor will shortly release its new NCP5680 10A LED driver to join its CAT3224 4A driver, and AnalogicTech is sampling a new version of its AAT1282, the AAT1282-4, which boosts output to 4A.
These supercapacitor-optimized LED flash drivers team with a thin CAP-XX supercapacitor to drive a WLED flash to full intensity, which a battery alone cannot do. The drivers integrate all circuitry required to charge the supercapacitor, manage in-rush current and control LED current, thus saving development time, board space and component cost.
More supercapacitor-optimized LED flash drivers are also in late-stage development at other PMIC companies.
New supercapacitor-powered LED flash module reference designs:
Both Seoul Semiconductor and ON Semiconductor have created LED flash module reference designs that demonstrate the thin-form BriteFlash solution: http://www.cap-xx.com/news/photogallery.htm#flashref
CAP-XX developed the BriteFlash Power Architecture to give designers a thin-form LED flash solution that delivers light energy that exceeds standard battery-powered LED flash, and rivals bulkier xenon flash.
