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. The new 100V-rated IRF7473 comes in an SO-8 package, and was designed for the primary stage of two-stage isolated converters with 48V input and 1.6V output at 60A. […]
Vishay Intertechnology Inc. (Malvern, PA) debuted a new entry into its series of LDO regulators. The company claims that the new Si9183DT is designed to provide power to the signal-processing circuitry in digital cellular phones and computers. Specified for input voltages between 2V and 6V, the Si9183DT is offered in seven low-noise versions with fixed […]
Sipex (Billerica, MA) has announced the availability of its new IC, the SP2526, an integrated 3V to 5V USB dual-power control switch, designed for self-powered and bus-powered USB computer peripherals. The SP2526 features soft-start, over-current protection, fault notification and enable/disable control. The two independent power switches source 500mA each and are controlled by separate enables. […]
Sipex Corp. (Billerica, MA) announced that revenue and earnings will be lower than the company expected for the fourth quarter.
