CAP-XX Product Comparison Photos

Pictured here with a US quarter dollar, CAP-XX supercapacitors benefit from a unique nanotechnology construction, which packs the highest energy and power-densities available today into thin, lightweight, prismatic packages (as little as 1mm thick). These ultra-slim supercapacitors provide the peak power required for high brightness LED flash (BriteFlash™), enhanced audio reproduction (BriteSound™) and many other applications (BritePower™).

The key advantage of LED Flash over Xenon in camera phones is size. An electrolytic capacitor is required for Xenon Flash and a slim supercapacitor powers an LED Flash. For instance, a SonyEricsson K800 uses two electrolytic capacitors each measuring 7mm dia. x 18mm long. The CAP-XX LED BriteFlash™ solution uses two supercapacitors measuring 17mm x 39mm x 1.1mm side by side to keep the solution very thin”

BritePower™ Solutions/Devices Using Supercapacitors

Perpetuum's PMG17 vibration energy-harvesting micro-generator, together with a CAP-XX supercapacitor, allow wireless sensor system manufacturers to design battery-free condition monitoring systems that collect and report data on machinery for improved asset management. The PMG17 microgenerator converts unused mechanical vibration into a low but steady source of electrical energy. The supercapacitor then stores the energy and delivers the peak power needed to transmit sensor condition data over wireless networks such as IEEE 802.15.4 (Zigbee) and 802.11 (WLAN). Together they can power wireless sensor nodes indefinitely.

BriteFlash™ Power Architecture for High-Res LED Flash Camera Phones

To demonstrate the increased flash power and ease of design-in, CAP-XX engineers retrofitted several industry-leading camera phones with the BriteFlash™ solution. In this phone, CAP-XX added a ~1.2mm thick dual-cell supercapacitor [highlighted in red], replaced existing LEDs with 4 high-powered LEDs that can each handle a peak pulse current of 1A, then put the phone together again with no change in external appearance. The original phone delivered 1 watt of flash power for 160 milliseconds while the CAP-XX-modified phone delivered 15 watts for the same amount of time.

CAP-XX placed two supercapacitor cells and four replacement LEDs in a leading-brand camera phone to demonstrate its flash power. The photos below were taken using the unmodified phone on the left and the CAP-XX-modified phone on the right. The unmodified phone delivered 1W of flash power for 160ms while the modified phone delivered 15W of flash power for 160ms.

Supercapacitor-based LED Flash:
High-current LEDs need up to 400% more power than a battery can provide to achieve full light intensity.
Supercapacitors can deliver the pulse power needed (>1A), allowing the battery to focus only on recharging the
supercapacitors between flashes while the supercapacitors drive the LEDs at very high current for the flash pulse.

The graph below shows the Battery Current, LED Current, and Supercapacitor Voltage during a flash pulse and supercapacitor recharge after the pulse. Note that the Battery Current never exceeds 300mA even though the
flash pulse is 4A. The supercapacitor provides the 3.7A difference.


BriteSound™ Power Architecture for Music Phones
Pump up the volume! Supercapacitors enhance audio quality and power in mobile phones. As multimedia and music phones grow in popularity, consumers want an iPod-quality audio experience without the buzzing and distortion associated with wireless transmissions. In the BriteSound™ power architecture, CAP-XX supercapacitors double audio power for richer-sounding music and handle peak power demands to eliminate distortion during wireless transmissions.
Audio Quality Problems in Music Phones
Typically, a standard 3.6-volt battery powers two class D amplifiers to drive a pair of 8-ohm speakers. For the problems with this typical set-up, see white paper.

Managing Mobile Phone Audio Power with a Supercapacitor
In the BriteSound™ power architecture, a 2.4mm-thin, 0.55-farad, 85-milliohm dual-cell CAP-XX HS206 supercapacitor delivers 5W power-bursts to drive peak-power functions such as audio and LED Flash. A battery covers the phone's average audio power needs of 0.5 to 1W, recharging the supercapacitor between bursts. This leaves enough battery power to handle data transfers and network polls without compromising audio power, eliminating both the distortion and "clicks" normally heard. The supercapacitor powers the audio amplifier at 5 volts, compared to 3.6 volts directly from a battery, thereby doubling peak audio power for full-sounding music with a strong bass beat. 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.

Tests Comparing Mobile-Phone Audio Quality and Power
CAP-XX used three cases for comparing audio quality and power, testing typical mobile-phone audio circuits both with and without a supercapacitor. To test the difference in power that 4-ohm versus 8-ohm speakers would make, CAP-XX simulated the effect by attaching a second set of identical 8-ohm speakers in the supercapacitor-powered set-ups. To test a bass beat and a network poll, CAP-XX built 2 test circuits each with two class D audio amplifiers, one powered by a battery to drive a pair of 8-ohm speakers, the other supported by a supercapacitor to drive two pairs of 8-ohm speakers.
Bass Beat
CAP-XX used a 100Hz bass beat lasting 120 milliseconds repeated every 0.5 seconds to test speaker power and battery current. The supercapacitor tripled peak audio power from 1.65W to 5.2W for fuller-sounding music. Test results are shown below in Table 1 and Figures 3 and 4. For more technical details, see white paper.

Network Poll
CAP-XX simulated a GSM/GPRS/EDGE network poll while listening to music by applying a two-amp, 1.15-millisecond power pulse while the audio amplifier was playing a 1KHz tone. The supercapacitor protected the audio amplifier from the battery voltage droop, eliminating distortion during wireless transmission. Test results are shown below in Figures 5 and 6. For more technical details, see white paper.

Fig 6: Supercapacitor buffers the audio amp from battery voltage droop during the RF transmit pulse, so there is no audio distortion

Listening to a Piece of Music
CAP-XX used a set of SonyEricsson MPS60 external speakers and audio amplifier as a test bed. Engineers modified one set with a supercapacitor charged to 5V to power the audio amplifier, then connected a second pair of 8-ohm speakers to the original pair. Figures 7 and 8 below show the modifications. The company played a piece of music to compare the unmodified MPS60 to the supercapacitor-powered one. The supercapacitor-modified setup more than doubled peak audio power from 2.24W to 4.96W, so music sounded fuller and richer. Test results are shown below in Figures 9 and 10 and Table 2. For more technical details, see white paper.
