Rui Rui semiconductor company launched the ultra compact 2 MHz 7 - 12 watts integrated boost high brightness LED driver solution

Simulation, high-speed Ethernet bandwidth and integrated circuit solutions of the industry's leading companies Micrel company today launched a portable equipment industry's smallest and most powerful LED driver solution MIC2299. This highly efficient DC to DC converter can guarantee 3.5 safe integrated conversion current, the net output power of up to 7 - 12 watts, and the use of 3mm x 3mm (R) micro package. MIC2299 mainly for mobile phones, PDA, digital cameras and emergency lights and other equipment, photographic flash and LED flashlight applications, has achieved mass production, starting at $1.7 per thousand pieces.

Micrel power company responsible for product marketing director Ralf Muenster said: "the Micrel MIC2299 can guarantee the conversion of 3.5 amps solution, the occupied area is only 0.25 square inches for portable equipment is high in the premise of precious battery life under the brightness of the LED drive to set up a new standard. In addition, the output voltage of the solution can be as high as 30 volts, which can achieve up to 8 high brightness series LED lighting. "

The MIC2299's powerful high current integrated switch enables the device to deliver at least 1 safe current to the two series of white LED or transmit the 750 Ma to the 3 series of white LED. In this way, the utility model can realize the strong flashlight illumination in the dark environment, or the bright flash effect of the purpose of improving the picture quality under the condition of low illumination. The brightness of the LED can be controlled by applying a voltage or a pulse width modulation signal on the brightness pin. The integrated circuit operates at a fixed switching frequency of 2 MHz with a maximum efficiency of up to 90%. The MIC2299 solution requires only a miniature low cross section sensor and a small ceramic capacitor, which greatly reduces the footprint and minimizes the cost of the solution. Finally, the solution with the current array architecture to match the battery operation, the input voltage is 2.510 volts.
