		<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>
