		<description><![CDATA[BIEL, Switzerland &#38; MILPITAS, Calif.&#8211;(BUSINESS WIRE)&#8211;IXYS Corporation (NASDAQ:IXYS) announces today sample availability of the LDS8640/41 and LDS8680/81, innovative 2 channels, charge-pump based, high efficiency LED drivers with low dropout voltage for Photo Flash applications. The drivers provide full output power from a single-cell lithium ion battery or supply voltage in the range of 2.7V to 5.5 V. The LDS8680 has two channels, one channel can drive one HB LED up to 800mA, and the other channel can drive up to 400mA. For flash applications using two HB LEDs, LDS8680 can simultaneously drive both HB LEDs at 400 mA each. The LDS8680 uses a patent pending SmartOne Wire™ interface to adjust LED currents ranging from 50 to 800 mA in 31 steps for one channel and from 50 to 400 mA in 15 steps for the other channel. It also allows PWM dimming to adjust LED brightness. Every channel may be turned on/off or programmed separately. The LDS8681 drives LEDs with a factory preset maximum LED current of 400 mA per channel and uses PWM dimming control for LED brightness adjustment. The LDS8640/41 family is similar in function to the LDS8680/81, but with lower current ratings. The LDS8640 can drive one channel up [...]]]></description>

		<description><![CDATA[SUNNYVALE, CA&#8211;(Marketwire &#8211; July 7, 2009) &#8211; Leadis Technology, Inc. (NASDAQ: LDIS), an analog and mixed-signal semiconductor developer of LED drivers, today announced sample availability of the LDS8680/81 and LDS8640/41, four new inductorless, dual-output LED flash/lamp drivers in low profile (0.8mm), space-saving 2x3mm TDFN packages. Targeted at camera-enabled handsets and digital still cameras, the LDS8680/81 and LDS8640/41 drive up to 800mA and 400mA, respectively, from a single Lithium-Ion battery. The LDS8680/81 and LDS8640/41 offer multiple advantages for system designers. For longer battery life, the efficiency is increased up to 90% in torch mode by the inclusion of Leadis&#8217; proprietary PowerLite™ Current Regulator. Simple and flexible controls in these new drivers make the system design easier. LED currents can be factory pre-programmed from 52mA to 400mA per channel eliminating the need for any external components. The two output channels can be operated independently; for example, one as the primary camera flash and the other for red-eye reduction. The on-chip automatic flash time-out can be programmed to either 250 or 500ms. In addition it is possible to realize a complete camera flash solution using the LDS8680/81 (or LDS8640/41) with only three external capacitors and no external resistors, resulting in both reduced board [...]]]></description>
