International Rectifier's New Technology Breakthrough Simplifies Power Management Design.Business Editors and Electronics/Semiconductor Writers 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.--(BUSINESS WIRE)--Feb. 23, 2001 International Rectifier International Rectifier Corp. (NYSE: IRF) is a manufacturer of power semiconductors (MOSFET, IGBT, diodes and thyristors), located in El Segundo, California, USA. It has a market capitalization of 2.48 billion USD and is listed on the S&P Midcap 400. Corp. (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 ) today introduced iPOWIR(TM) technology, a whole new way to design on-board DC-DC DC-DC Direct Current to Direct Current (power conversion) converters for computing and communications equipment. Power demands for digital ICs are constantly increasing while size of converters to power these ICs must be minimized. IR's iPOWIR technology is a breakthrough in power density, efficiency and simplicity for power conversion. With iPOWIR technology, all layout-critical power semiconductor and passive components of the circuit are integrated to form complete functional building blocks, reducing converter size as well as simplifying and reducing power system design time. Typical iP2001 applications include power supply circuits for desktop, server and workstation CPUs, as well as network processing units Network Processing Unit or NPU is an array of one or more Central processing unit (CPU) whose instructions are specialized to handle networking-related functions. NPUs are generally targeted at efficient examination and manipulation of packet headers. (NPUs) and application-specific ICs (ASICs) used in networking, telecom switchers and routers. "The iPOWIR architecture is an example of IR's power management expertise in all areas and is much more than simply integrating functions. Benchmark power semiconductors are matched with control ICs, optimized packaging and advanced system design. Only when all of these aspects are combined can complete functionality be bundled into a tiny, easy to design solution. International Rectifier's iPOWIR architecture gives our customers the simplest path to the highest power density," said Gene Sheridan, International Rectifier Vice President of Application Sector Management. The First iPOWIR(TM) Device The iP2001 is the first iPOWIR component, a high-current, multiphase Mul´ti`phase a. 1. (Elec.) Having many phases; Adj. 1. multiphase - of an electrical system that uses or generates two or more alternating voltages of the same frequency but differing in phase angle DC-DC converter power building block, housed in an 11mm square package. The term "multiphase" refers to an advanced power management technique for high-current power supply systems in which the total load is shared evenly between several phases. For example, a two-phase, 30 amp power supply using the multiphase technique would have two phasing circuits running 15 amps each. "The new generation of power hungry ICs are forcing the use of more complex power conversion circuits than ever before. This means the interaction between the analog ICs with power components is critical; even stray inductances between discrete components An elementary electronic device constructed as a single unit. Before integrated circuits (chips), all transistors, resistors and diodes were discrete. They are widely used in amplifiers and other devices that use large amounts of current. can cause significant performance variations. This causes the designer considerable layout difficulties in obtaining the highest performance. The integration of the layout-critical ICs and power components with iPOWIR technology offers the designer a layout-independent solution that is small, quick and easy to design with," said Chris Bull, Senior Product Marketing Manager responsible for the iPOWIR product range. The iPOWIR architecture can increase DC-DC conversion efficiency by as much 6%, reduce power loss as much as 25% and shrink size from 44% to 58% when compared with some circuits using discrete components or modules. Future Developments "New iPOWIR solutions will enable power supply designers to achieve higher current density, hitting 20 and even 25 amps in existing form factors. The iP2001 is only the first chapter in this very innovative and flexible platform, which can be applied to any power conversion system where design simplicity and power density are of paramount importance," Bull continued. Availability At present IR is alpha sampling this new technology with mass sample availability due in June/July 2001. Production is scheduled for Q4 2001.
