ZANE International Inc. (Grand Junction, CO) recently announced the OEM dc voltage doubler. With a conversion efficiency approaching 99 percent at full-load, zero additional heat sinking is normally required for the approximately 2" square module, according to ZANE. Delivering 100 times the output of a conventional doubler with only 0.1V ripple at full-load, this doubler […]
Semtech Corp. (Newbury Park, CA) debuted a new power-management device that integrates a dc/dc switching regulator controller and two linear regulators, intended to provide the three distinct voltage levels required in new Pentium III-based systems and other tri-mode power-supply applications. Semtech claims that the new SC1109 device reduces component count, board-space requirements and has a […]
AVX Corp. (Myrtle Beach, SC) has named John S. Gilbertson the company's new CEO effective July 25, 2001. He will be replacing Benedict P. Rosen, who will remain AVX's chairman. Gilbertson joined the company in January 1981, and has served in various management assignments since then. He was elected COO in 1994 and president in […]
IXYS Corp. (Santa Clara, CA) has introduced two new IGBTs, the IXLF19N220A and IXLF19N250A, with blocking voltages of 2,200V and 2,500V respectively. The two new IGBTs have the same current rating of 19A and come in a new, electrically isolated, discrete package called the ISOPLUS i4-PAC. In this new plastic-encapsulated package, a direct-copper-bonded alumina substrate […]
Advanced Power Technology Inc. (Bend, OR) announced the introduction of a new line of high-voltage RF MOSFETs. The company claims that they have developed a new process for making RF amplifier MOSFETs that doubles the available safe operating area, improves the resistance to load mismatch, and expands the capacity to run in the linear mode, […]
International Rectifier (El Segundo, CA) has released a new series of topology-specific HEXFET power MOSFETs that they claim maximize efficiency in targeted, isolated and buck dc/dc converters.
