A Morimi 10 A super capacitor LED flash drive

The world's leading high performance and high efficiency silicon solutions provider A Morimi (ON Semiconductor) semiconductor light emitting diode after launch NCP5680 optimization of super capacitor (LED) flash drives, for thin and compact digital camera mobile phone camera flash and video camera lights (video light) to provide up to 10 amps (A) current.

A Morimi semiconductor low-voltage power management product director Marie-Therese Capron said: "NCP5680 is a combination of ultra-thin prismatic super capacitor, provides an excellent LED flash and a power management scheme for ultra-thin mobile phone camera and digital camera. This comprehensive LED flash scheme is comparable in luminosity to xenon flash, but is only half the height of the latter, and does not require an additional LED to shoot video. NCP5680 makes lithium-ion batteries to make more power consumption can work longer hours, this new super capacitor based power management program allows smart phones can provide a more rich features. "

A Morimi semiconductor NCP5680 combined with the latest slim prismatic super capacitor, such as capacitor voltage provided by CAP-XX and Murata authorized 5.5 V capacitor is 0.9 F, and the OSRAM provided LED OSLUX NCP5680 high power lithium ion battery and complement each other, provide high peak current up to 10 A for flash lighting, and CAP-XX the development of BriteFlash with the use of power architecture and optimization?. Fully programmable controlled super capacitor charging and discharging and unique overload protection to ensure proper light for high quality photography. NCP5680 this integrated driver can also be used in other large peak current circuits such as audio amplifiers and other portable systems to extend useful battery life.

5 million pixels or higher resolution camera in order to take high resolution photos under weak light, the need for high brightness flash. Today's white LED is able to provide this level of light, but need to be able to provide more than 400% of the energy provided by the camera battery. A Morimi semiconductor NCP5680 with the battery, the management of a super capacitor to drive the LED flash to full brightness, providing up to 10 A peak current. NCP5680 integrated driver in the management of the super capacitor, the other peak power functions, such as zoom, auto focus, audio, video, wireless transmission, global positioning system (GPS) data read and radio frequency (RF) amplifier, extend the time without giving up the slim type design of battery.

The NCP5680 integrates all the circuitry required for super capacitor charging, inrush current management, and LED current control, saving the developer's development time, board space and component cost. Super capacitor charging and discharging fully programmable control to ensure high quality photography to provide the appropriate light.

Provide flexible control with I2C interface

The I2C register in the NCP5680 allows the user to adjust the output current and flash duration of each LED in two LED in real time. Therefore, this scheme can provide different lighting effects, such as light, flash, camera power flash, and video recording flashlight. When NCP5680 is connected to the ambient light sensor, it will automatically limit the duration of the flash, and prevent excessive exposure to ensure the quality of the photo. In addition, the super capacitor charging current can be adjusted by I2C register. NCP5680 can shut down the charge during the global mobile communication system (GSM) transmission, thus limiting the battery current consumption.

Safety protection characteristics

NCP5680 also has a number of built-in protection mechanisms, including flash timeout (flash time out), temperature detection, overload protection and short circuit protection. This device protects the flash circuit from the driver circuit and any impact of the LED fault.

Package and price

NCP5680 uses 3.5 mm x mm x 0.55 mm QFN-24 package, each of the 3000 pieces of the budget unit price of $1.10 in 3.5.
