Austria microelectronics to create a new 8A LED flash drive

Leading IC and sensor suppliers Austria microelectronics company on high performance analog before announcing the launch of a LED flash drive, flash light output brings remarkable for the intelligent mobile phone, compared with today's smart flash system is widely used in the mobile phone can be realized at least four times the brightness of the light output.

The newly launched AS3630 flash driver can drive up to 8A of the current, enabling the camera to achieve high resolution photo shoot. Before the dark light shooting fast-moving objects, the photos will produce smearing, and now you can accurately capture the details at the same time, to prevent glare and discomfort, because even as low as 10ms flash duration has been able to provide enough flash light.

Compared with the LED flash drive, which provides the highest 2A output power in the mobile phone today, the AS3630 has a brightness output of up to 4 times and supports faster shutter speeds.

The AS3630 8A LED flash driver uses an innovative architecture that takes advantage of the energy stored in the supercapacitor (double layer capacitor -EDLC), which is currently being patented. When driving two series of LED lights, the driver will increase the output voltage from the 5.5V of the super capacitor to LED higher than the 9V to meet the forward voltage requirements. When the output voltage of the independent capacitor is less than LED, the boost topology of the device can also make the flash lighting last longer. The architecture allows the use of very small capacitors.

The AS3630 flash driver can use both the electric energy and the battery stored in the super capacitor, and can support the additional functions such as pre flash, video shooting and lighting, etc..

Two tandem drive flash LED can provide consistent light output. In high power flash applications, the parallel LED architecture often results in a huge difference in output light due to differences in the production of LED lamps. Austria microelectronics series LED architecture, the perfect match from the two flash LED light output, so that it is not affected by the forward voltage difference LED.

In order to optimize the system performance, Austria microelectronics and passive components manufacturer has Murata (Murata) cooperation, many performance advantages of AS3630 by Murata collocation of lightweight and high capacity of electric double layer capacitors can be realized.

Austria microelectronics company optical sensor and lighting Marketing Manager Oliver Weber said: "when the AS3630 collocation such as Murata DMF series high performance electric double layer capacitor, can significantly improve the intelligent mobile phone camera picture quality, while maintaining the appearance of thin highly favored consumers. "

AS3630 8A LED flash drive is now mass production.
