White LED driver for lighting organic EL panels IC

California Micro Devices Corp (California Micro Devices, CMD) recently developed the "CM93xx" series of white LED driver IC, including the series can provide lighting varieties for the organic EL panel (release). Including can drive 2 sets of LED and organic EL panel "CM9321", can drive the single set of LED and organic EL panel "CM9311", can drive 3 sets of LED "CM9330", and can drive 2 sets of LED CM9320". Dezhou food and other companies have developed a white LED driver can provide lighting for organic EL panel IC. In addition, California Micro Devices Corp has developed a set of up to 6 LED can drive up to the "CM913x/4x" series and the output voltage is fixed to 4.5V "CM915x" series (published information).

CM93xx series output voltage range of 2.7 ~ 6V. The output voltage is 20V. Control by issuing 1MHz PWM signal. CM9330 and CM9321 are available in the 4mm square 16 pin TQFN package, the CM9320 and CM9311 are packaged in a 3mm square, 10 pin TDFN package. At present, the sample has been started, the price of 100 yuan per batch purchase from $1.2. Planned for the second quarter of 2006 into mass production.

CM913x/4x series and CM915x series input voltage range of 2.9V ~ 6V and 3 ~ 6V. The charge pump circuit is built, the step-up ratio is 1 times and 1.5 times, respectively. Samples are now available for purchase at a price of $0.6 per 1000 units. Production is scheduled for the second quarter of 2006. (reporter: root Jin Zhen)
