Minimum 3 LED drives in industry with a 3 x mm package

MicrEL (Inc.) introduced the industry's smallest and most powerful portable devices for light-emitting diode (LED) driver - MIC2298. This device is a 7 Watt High Efficiency Boost DC to DC converter in a small 3mm x 3mm MLF package. MIC2298 for mobile phones, personal digital assistants (PDA) and digital cameras, flash and flashlight lighting applications.

"Mobile phones and PDA have greatly improved the camera pixels they offer to consumers," said Ralph Mnster, head of the company's marketing of power products. However, even these high - pixel cameras are still in poor performance in low light conditions. The new MIC2298 LED driver enables the designer to use a high brightness LED flash to improve the performance of its integrated camera, and the space and the required battery power are the smallest in the industry. "

The MIC2298 ensures a 3.5 safe conversion current, allowing the device to provide a current of up to 1 in a series of high brightness white light emitting diodes (WLED) connected in series (two). This gives rise to a bright flash to improve the quality of the photos, especially for the 2 million or more pixels. The brightness of the light emitting diode can be controlled dynamically by applying voltage or pulse width modulation (PWM) signal to the brightness setting pin. The integrated circuit works at a fixed switching frequency of 1MHz, and the efficiency is above 86%. This high efficiency makes the battery lifetime longer, coupled with its small size, the Marie MIC2298 become the best solution for driving high brightness light-emitting diode advanced mobile phone and PDA equipment in the.

The MIC2298 solution requires only a small 2.2uH sensor and a small ceramic capacitor to minimize the volume and minimize the cost of the solution.

MIC2298 LED driver enables designers to use a high brightness LED flash to improve the performance of its integrated camera, and the space and the required battery power for the industry.
