Prime Minister visits Zetex
Tony Blair has visited Zetex Semiconductor’s Oldham Headquarters during a fact-finding trip to the North West of England. He was accompanied on a one hour tour of the Zetex Technology Park by Zetex Chief Executive Officer Hans Rohrer.
LED driver is said to increase 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. Achieving up to 95% efficiency, this LED driver’s thermally enhanced con...
Monitor simplifies current measurement at high voltages
With an operating range of 3V to 40V, the ZXCT1081 current monitor from Zetex Semiconductors provides a very simple high voltage current measurement solution for automotive, industrial and power supply applications.
MOSFETs suit ultra low gate drive operation
Zetex Semiconductors has introduced three new N-Channel enhancement mode MOSFETs, developed specifically for applications with limited drive voltage availability. The 20V ZXMN2B03E6 (SOT236), ZXMN2B14FH and ZXMN2B01F (both SOT23) are capable of low loss switching at a VGS of 1.8V, enabling them to be operated from two 1.2V cells or a single Li-Ion cell. Their ultra low gate drive also means they can be driven directly by logic gates.
Class D amplifier reference designs from Zetex
Zetex Semiconductors has announced a series of subwoofer amplifier reference designs using a unique feedback architecture to minimise distortion and noise and achieve the high damping factors required for tight bass control.
Class Z chipset uses direct digital feedback amplifier (DDFA) technology for a listening experience to rival the best linear amplifiers
Comprising the ZXCZM800 multi-channel digital modulator and the ZXCZA200 analog feedback processor, a digital amplifier chipset from Zetex Semiconductors has been introduced to create audio products capable of producing a sound quality to rival that of the best linear amplifiers. Based on Zetex Semiconductors’ unique Class Z direct digital feedback amplifier (DDFA) architecture, the chipset enables high performance products suc...
Zetex appoints Taiwan country manager
Zetex Semiconductors has made Tim Chen its Country Manager for Taiwan, with responsibility for local business development for the company’s broad portfolio of audio, DBS, LED lighting and power management solutions.
Zetex announces technology breakthrough in LNB design
A 4:2 IF switch announced by Zetex Semiconductors is the world’s first to feature integrated gain and control functions. Dramatically improving IF signal reliability, eliminating false switching and significantly reducing circuit complexity, the ZXHF5000 chip is set to have a far-reaching impact on the design of twin and quad LNBs and satellite TV distribution networks.
Zetex appoints Davy Lo as Chief Marketing Officer
Davy Lo has been appointed Chief Marketing Officer for Zetex Semiconductors’ ASSP business group, with responsibility for the company’s rapidly expanding range of audio, DBS, LED driver and LED power management products. Lo joins Zetex after 26 years with Texas Instruments in senior Marketing and Sales roles based in Asia. He was most recently Director responsible for Marketing and Sales at Texas’ Hong Kong office.
Zetex grows European team by three
No less than three new people, Peter Devilée, Robert Gabriel and Peter Lüns, have joined Zetex Semiconductors’ European sales and application engineering team to support the company’s expanding range of discrete and integrated analogue semiconductor products.
Zetex Semiconductor appoints Dr. Franz Riedlberger as CTO
Zetex, the analogue semiconductor company, has announced that Dr. Riedlberger, an accomplished semiconductor industry veteran, is to head its technology department. “This is another important milestone for Zetex, demonstrating our determination to put a world-class team in place to excel in achieving our ambitious goals,” said Chief Executive Hans Rohrer. “Franz brings a wealth of knowledge to the company, both in semiconductor technology ...
Zetex gets new VP for Asia Pacific
Zetex Semiconductors has strengthened its presence in the Asia Pacific region through the appointment of Echo Li as Vice President Sales. Based at the company’s Hong Kong office, Echo will be responsible for local sales strategy for the Zetex range of audio, DBS, lighting, motor control and power management products.
Mid-voltage transistors increase circuit power density
Zetex Semiconductors has introduced a range of mid-voltage bipolar transistors in the SOT23 package, capable of handling a power dissipation of up to 1.25W. With the 3mm x 2.5mm footprint, these seven NPN and six PNP devices help to significantly increase circuit power density by replacing the much larger DPAK, SOT89 and SOT223 packaged parts.
MOSFETs meet Class D audio amplifier needs
A new generation of trench MOSFETs from Zetex Semiconductors has been introduced to provide the high efficiency, cool running and quality audio reproduction demanded by Class D output stages. Rated at 70V, and offered in SOT223 and DPAK packages, these N- and P-channel devices ensure reliable, safe operation in higher power audio applications including flat panel TV and 5.1 surround sound systems. The selection will suit single-ended and bridge...
LED driver is easy to use
Requiring a single external resistor to very accurately set its output current, the ZXLD1350 from Zetex Semiconductors simplifies high power LED driving. Operating from an input supply of between 7V and 30V, the driver can produce an adjustable output current of up to 350mA, to support an LED chain of up to eight 1W LEDs.
High Voltage MOSFET is optimised for power supply start-up
A high voltage MOSFET from Zetex Semiconductors has been introduced to handle the requirements of pre-bias supply circuitry. A 450V enhancement mode N-channel device, the ZXMN0545G4 is used in a simple linear regulator to supply PWM ICs at start-up, and is disabled once the converter is fully on.
Current monitor enables true short circuit current monitoring
With its wide common mode sense range of 0V to within 2V of the supply voltage applied, the ZXCT1051 current monitor from Zetex Semiconductors enables true short circuit current monitoring.
Miniature bipolar package increases power supply efficiency
Combining complementary NPN and PNP transistors in the SOT236 package, the ZXTC2045E6 from Zetex Semiconductors produces the drive requirement needed to switch high power MOSFETs and IGBTs in power supply designs.
