Intersil Introduces Advanced Regulator Chip Set Which Solves Power Challenges in Next-Generation Intel-Based Computing Platforms.Business Editors/High-Tech Writers Intel Developer Forum Intel Developer Forum (IDF), is a twice yearly gathering of technologists to discuss Intel products and products based around Intel products. The first IDF was in 1997. There is usually a Spring IDF and a Fall IDF. Spring 2004 MILPITAS, Calif.--(BUSINESS WIRE)--Feb. 9, 2004 Intersil Corporation (Nasdaq:ISIL ISIL International Society for Individual Liberty ISIL Interim Support Items List ISIL Intelligence Systems Integration Laboratory (Ft. Huachuca, Arizona; US Army facility for integrating intelligence systems) ): -- Most Highly Integrated ACPI-Compliant PC Power Regulator Chips in the Industry -- Chip Set Offers Highest Performance While Reducing Space, BOM Cost and Routing Complexity Intersil Corporation (Nasdaq:ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced two new Endura(TM) power regulator ICs specifically designed to provide reduced bill-of-materials, manufacturing costs, board space and routing problems for the next-generation Intel-based computing platforms.

E-mail: Bill Janssen <janssen@parc.xerox.com>. 6537 and ISL6506 offer an unmatched level of regulator integration with the capability of regulating six different PC motherboard voltages with full ACPI (Advanced Configuration and Power Interface) A power management specification developed by Intel, Toshiba and Microsoft that makes hardware status information available to the operating system. compliance. These ICs deliver the highest performance-to-price value in the industry for leading-edge high-end workstations, servers and PCs. The Advanced Configuration and Power Interface See ACPI. (hardware, standard) Advanced Configuration and Power Interface - (ACPI) An open industry standard developed by Intel, Microsoft, and Toshiba for configuration and power management. (ACPI) specification is an industry standard that enables system power components to be software controlled in real time to improve power and operating system efficiency. ACPI-compliant power ICs are essential to realizing these benefits. "Intersil is the recognized power solutions expert, focused on high-end, highest-performance, workstations, file servers and desktop PCs," said Cindy Drapcho, Vice President for Intersil's Desktop and File Server Power Products. "Customers look to us to provide higher electrical performance, better thermal efficiency, ease-of-use, lower solution component count (up-integration), smaller solution footprints and lower overall bill-of-materials cost. Our new ISL6537 and ISL6506 are prime examples of how we satisfy the needs and expectations of our valued customers." The ISL6537 and ISL6506 offer an unmatched level of integration, regulating a total of six motherboard voltages: the DDR (Double Data Rate) Refers to an SDRAM memory chip that increases performance by doubling the effective data rate of the frontside bus. For more details, see SDRAM. DDR - Double Data Rate Random Access Memory memory core, DDR termination, chip set core, 5 V(dual), 3.3 V(dual), as well as the CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. bus termination voltage. While these ICs can be used separately, the two as a set offer the greatest performance improvement along with space and cost savings. The ISL6506 works well to complement the ISL6537 providing the 5 V(dual) that the ISL6537 requires for down-conversion to the DDR core and the other voltages. The ISL6537 offers higher performance and greater cost savings than previous solutions. This advanced IC integrates one PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a controller, one 3-A low dropout (LDO LDO Low-Dropout (Used With Regulators) LDO Limited Duty Officer LDO Light Diesel Oil (petroleum) LDO Local Development Officer (Nepal) LDO Land Development Ordinance ) regulator, and two LDO controllers, along with all the power sequencing, system monitoring and protection functions required for DDR and chip set regulation on Intel-based motherboards. The ISL6537 reduces critical board area and overall BOM cost while maintaining ease of routing and thermal margin to meet higher power density requirements of next-generation Intel CPUs. The integration of four (4) regulators in the ISL6537 contributes strongly to space and cost savings while enhancing performance and reliability. The ISL6537 provides a complete ACPI-compliant power solution for up to four (4) dual in-line memory module See DIMM. (storage) Dual In-line Memory Module - Small circuit boards carrying memory integrated circuits, with signal and power pins on both sides of the board, in contrast to single-in-line memory modules (SIMM). (DIMM (Dual In-Line Memory Module) A printed circuit board that holds memory chips and plugs into a DIMM socket on the motherboard. See memory module. DIMM - Dual In-Line Memory Module ) dual-channel DDR/DDR2 memory systems. The synchronous buck controller supplies VDDQ during the S0/S1 and S3 states. During the S0/S1 state, a fully integrated 3-A sink-source regulator generates an accurate (VDDQ/2) high-current VTT voltage without the need for a negative supply. A buffered version of the VDDQ/2 reference is provided as VREF VREF Voltage Reference VREF Reference Voltage VREF Vancomycin-Resistant Enterococcus Faecium (antibiotic-resistant bacteria) VREF Reference Landing Speed (aviation) VREF Vertical Refresh . Two on-chip LDOs provide graphics memory controller hub (GMCH GMCH Graphics and Memory Controller Hub GMCH Graphics Memory Controller Hub ) core voltage regulation and GMCH/CPU VTT bus termination voltage regulation. The ISL6537 GMCH core LDO is a dual-stage LDO. The DDR core voltage is stepped down to an intermediate voltage, and this intermediate voltage is stepped down to the desired GMCH core voltage through a second power MOSFET. This provides the benefit of spreading the thermal dissipation on the motherboard, reducing the size of the MOSFETs, and the PCB PCB: see polychlorinated biphenyl.

Higher performance and additional cost savings are provided by Intersil's new ISL6506 ACPI-compliant dual regulator, which was designed to serve stand-by system and peripheral power requirements.
