Intersil has introduced a two-phase core controller with embedded gate drivers to power AMD’s next-generation (64-bit Turion) mobile CPUs. The device offers improved transient response and load line accuracy enabled by the company’s patented R3 (Robust Ripple Regulator) Technology. The controller uses post package trimming to remove all errors associated with assembly and offers 0.5% accuracy across the entire temperate range, which is the best in the industry. The ISL6264 uses two interleaved channels to double the output voltage ripple frequency, reducing output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation and smaller real estate area.

6. Slow recovery in U.S. computer growth. PC spending momentum turned positive in October 2009. (2009 growth: minus 11.1 percent; 2010: plus 1.6 percent; 2011: plus 6.3 percent).

7. Semiconductors recover sooner than other industries, up sharply in 2010 and regaining 2008 levels of activity in 2011. Semiconductor full recovery in 2011.

Vishay Intertechnology, Inc. has unveiled a new bidirectional symmetrical (BiSy) single-line ESD protection diode in the LLP1006 package.

The compact VBUS05L1-DD1-G-08 provides a low capacitance of 0.3 pF for the protection of antennas, USB 3.0, and HDMI ports from transient voltage signals in portable electronics.

Featuring a compact 0.6-mm by 1.0-mm footprint with a very low package height of <0.4 mm, the VBUS05L1-DD1-G-08 minimizes the board space required for active ESD protection in devices such as portable gaming systems, digital cameras, MP3 players, and mobile phones.

At the working voltage of 5.5 V, the diode offers a high isolation to ground characterized by a low leakage current of <0.1 microamp. Any transient voltage signal exceeding the reverse breakthrough voltage of typical 8.4 V at 1 mA will be "clamped" or "short" to ground. The device features a maximum clamping voltage of 14 V at 1 A.

Due to the short leads and small package size of the LLP1006, the diode's line inductance is very low, allowing fast transients such as an ESD strike to be clamped with minimal over- or undershoots.

The VBUS05L1-DD1-G-08 provides transient protection for one data line as per IEC 61000 4 2 at ±9 kV (air and contact discharge). The device is lead (Pb)-free and complies with RoHS 2002/95/EC and WEEE 2002/96/EC. To lower manufacturing costs, soldering of the diode can be checked by standard vision, eliminating the need for X-ray inspection.

Sidense's OTP macros combine very low power, a small footprint and ease of programming, which helped Audium develop the most efficient audio power amplifier over normal listening levels in the industry,” said Huw Davies, chief commercial officer for Audium, in a statement issued by Sidense.
