An updated study has been published by Limited, developer of thin-form supercapacitors that compare flash solutions for camera phones – xenon, standard LEDs powered by a battery, and high-current LEDs powered by a supercapacitor using the company’s BriteFlash(TM) power architecture. The study tested each solution’s ability to deliver the light energy needed to take digital-still-camera-quality [...]
Advanced Analogic Technologies has introduced a 2-MHz boost-converter IC that uses a supercapacitor to provide a large peak current to an LED-flash system. The 2A AAT1282 flash driver incorporates I2C control and accepts input voltages of 2.7 to 5.5V. Designers can use the device’s two 1A current sinks to drive two LEDs and can parallel [...]
LED Flash enables better image quality for next generation mobile camera devices. Combining high lumen output with the small form factor of LED Flash gives mobile handset makers a way to increase the quality of images for their customers. LED Flash LEDs produce flash illumination that is up to 12 times brighter than today’s devices, [...]
