| LED lighting driver increases power density | |
Providing an adjustable output current of 1A from a SOT23 package, the ZXLD1360 LED driver from Zetex Semiconductors offers higher power density than alternative and much larger SO8 devices. A buck regulator device, it operates over a supply range of 7V to 30V and is capable of handling up to 24W of output power in a wide range of high power LED illumination applications. |

| Infineon Drives Digital Mobile TV with Innovative and Energy-Efficient Tuner IC Solutions | |
Munich, Germany and Barcelona, Spain – Infineon Technologies today announced two new highly integrated, power-efficient DVB-H/T chip solutions: OmniVia™ TUS9090 and OmniTune™ TUA9000. OmniVia™ TUS9090 is a fully integrated System-on-Chip (SoC) that includes the RF Tuner, DVB-H/T demodulator and integrated memory. OmniTune™ TUA9000 is a direct-conversion multi-band Silicon Tuner (VHF, UHF as well as the L-Bands for Europe and North America) for the reception of both DVB-H and the DVB-T Digital TV transmission signals. These products target mobile digital TV applications such as mobile phones, PDA’s, mobile media players and laptops. Enabling miniaturization of electronics system design, the two new Infineon solutions will drive towards lower system costs, reduced power consumption and eventually an increased adoption rate of Mobile TV technology and applications. |

| Analog Devices Debuts The Industry’s Smallest, Most Flexible, Multichannel Converters | |
Analog Devices, Inc. today introduced the industry’s smallest and most flexible, multichannel digital-to-analog converters (DACs). Ideal for designers needing flexibility when specifying converters for high-voltage applications, such as factory process control, instrumentation and dc set-point-control applications, the offering includes 12 converters ranging from 12- to 16-bit dual and quad channel devices operating over a wide voltage range on either single or dual power supplies. In addition, the highly configurable DACs feature software-programmable, unipolar and bipolar voltage output ranges that can be independently set per channel. This gives designers the option to eliminate a number of discrete components, such as precision resistors, switches, and external amplifiers. Housed in small, pin-compatible, TSSOP (thin-shrink small-outline) packages, the converters are more than 40 percent smaller than comparable devices. Eliminating discrete components, plus the small package size, translates into board space savings of as much as 70 percent, when compared to existing discrete solutions. |
