IR HEXFET(R) MOSFET Chip Set Delivers up to 2 Percent Higher Efficiency in Two-Phase DC-DC Buck Converters.EL SEGUNDO El Segundo (ĕl sēgŭn`dō), industrial city (1990 pop. 15,223), Los Angeles co., S Calif., on Santa Monica Bay; inc. 1917. Its products include navigation and computer systems, aircraft parts, office machines, telephone apparatus, and , Calif. -- International Rectifier, IR(r) (NYSE NYSE See: New York Stock Exchange :IRF IRF Interferon Regulatory Factor IRF International Religious Freedom IRF Institut for Rationel Farmakoterapi (German) IRF Inherited Rights Filter (Novell) IRF Inherited Rights Filter ), a world leader in power management technology, today introduced a pair of 30V HEXFET HEXFET Hexagonal Field Effect Transistor (r) power MOSFETs that deliver up to 2% higher light-load efficiency over solutions using 30V MOSFETs in 45A, two phase synchronous buck converters powering the latest Intel and AMD (Advanced Micro Devices, Inc., Sunnyvale, CA, www.amd.com) A major manufacturer of semiconductor devices including x86-compatible CPUs, embedded processors, flash memories, programmable logic devices and networking chips. processors for notebook and other high performance computing applications. These new lead-free devices, the IRF7823PbF and IRF7832ZPbF, maximize efficiency and power density by optimizing conduction, switching and body diode losses. The two devices are designed to be used as a chip set in two-phase synchronous buck converter circuits requiring one control and two synchronous MOSFETs per phase. The new SO-8 MOSFETs are also suitable for other PWM-controlled DC-DC DC-DC Direct Current to Direct Current (power conversion) buck converter applications. "High efficiency, under low and intermediate power levels, is important in notebook applications since this is where most of the battery power is consumed. In this setting, our new chip set can deliver up to 2% higher efficiency in the 5 amp to 15 amp range," said Jeff Sherman, International Rectifier, senior marketing manager, Portable Computing Solutions. "The lower power losses achieved by these new devices also contribute to systems that run cooler, another very important aspect for portable computing," he added. The chip set consists of a control MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged and a synchronous MOSFET, with each device tailored to maximize performance in their role. Control MOSFETs have reduced switching losses (gate charge), while synchronous MOSFETs have low conduction losses (low on-resistance), and low reverse-recovery charge. The IRF7823PbF is an optimized control FET FET: see transistor. (Field Effect Transistor) One of two major categories of transistor; the other is bipolar. FETs use a gate element that, when charged, creates an electromagnetic field that changes the conductivity of a silicon , with very low gate charge and gate-to-drain charge of only 9.1nC and 3.2nC, respectively. The IRF7832ZPbF has been optimized for the synchronous FET function, with extremely low typical 4.5V on-resistance of 3.7mOhm, and is suitable up to 12A. Data sheets for the devices are available on the International Rectifier Web site: http://www.irf.com/whats-new/n5060131.html Availability and Pricing The IRF7823PbF and the IRF7832ZPbF are available immediately. Pricing is US $0.50 each for the IRF7823PbF, while the IRF7832ZPbF is US $0.88 each in 10,000-unit quantities. Prices are subject to change. The devices are lead-free and are compliant with the Restriction of Hazardous Substances Directive The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment 2002/95/EC[1] (commonly referred to as the Restriction of Hazardous Substances Directive or RoHS (RoHS).
