Also pictured (left) for comparison is the Nokia N82 xenon flash solution with its large, cylindrical electrolytic capacitor.
To demonstrate the increased flash power and ease of design-in, CAP-XX engineers retrofitted several industry-leading camera phones with the Brite Flash solution.
The supercapacitor also reduces noise by supplying peak power with less voltage droop than the battery would, and eliminates any 217Hz buzz when a GSM/GPRS/EDGE phone transmits by protecting the audio amplifier from other peak loads the battery supplies such as the RF Power Amplifier.
Because the supercapacitor supplies high-peak currents, designers can use higher-quality 4-ohm instead of standard 8-ohm speakers, further doubling peak audio power.
The image on the right compares the electrolytic capacitor used in the Sony Ericsson K800 and the supercapacitor used for the LED Flash.
The Sony Ericsson K800 uses two of these electrolytic capacitors each measuring 7mm dia. Similarly, the LED Flash solution uses two of these supercapacitors measuring 17mm x 39mm x 1.1mm side by side to keep the solution very thin.

The CAP-XX LED Brite Flash solution uses two supercapacitors measuring 17mm x 39mm x 1.1mm side by side to keep the solution very thin This wireless power module combines Powercast's RF energy-harvesting technology with a CAP-XX supercapacitor to create a perpetual, battery-free power source for the wireless sensors commonly used in security, environmental and condition-monitoring systems.
The module integrates a power receiving antenna, a Powercast Powerharvester to convert the radio waves into low DC power and a CAP-XX supercapacitor.
Integrating the circuitry outlined in blue (boost converter, supercapacitor balancing, I2C interface and LED current control), new supercapacitor-optimized LED flash drivers from major IC companies such as Analogic Tech and ON Semiconductor are now available to save time, board space and component cost. This supercapacitor-powered LED flash module reference design (pictured below), developed by Seoul Semiconductor, uses a thin, prismatic HA230 CAP-XX supercapacitor and an Analogic Tech AAT1282 LED flash driver (on reverse side) to drive high-current Seoul Semiconductor LEDs.
