Intel Developer Forum (IDF) – SAN FRANCISCO, Calif. – Sept. 14, 2010 – ON Semiconductor (Nasdaq: ONNN), a premier supplier of high performance, energy efficient silicon solutions for green electronics, has launched a portfolio of products that simplify and speed the design of computing platforms – including those built around the upcoming 2nd Generation Intel® Core™ Processor Family (Codename Sandy Bridge). The new products include high efficiency power management devices and advanced ICs for implementing high-bandwidth communication interfaces while reducing power consumption and saving board space.
“Our strategy has been to develop a complete platform of products that enable computer OEMs to simplify their design and development,” said Bill Schromm, ON Semiconductor senior vice president and general manager of Computing and Consumer Products. “We now offer solutions that address every major subsystem in desktop, notebook and netbook computing – including CPU power delivery, thermal management, power conversion in supplies and adapters, and high-speed interface switching and protection. With the addition of our newest controllers, MOSFETs and switches, ON Semiconductor can provide all the key semiconductor building-blocks required for next generation computing products – including those built around the upcoming 2nd Generation Intel® Core™ Processor Family (Codename Sandy Bridge).”
Among the ON Semiconductor products making their debut at IDF next week will be advanced controller ICs for CPU voltage regulation; a new family of high-efficiency High Side Voltage Regulation (HSVR) MOSFETs; and the company’s first products in a family of switches designed for common high-bandwidth communications interfaces. These technologies further expand ON Semiconductor’s platform solutions for desktops, notebooks and servers, which also include system rail devices and components for protection and thermal management.
“We are pleased that the smart performance and new visual capabilities of the 2nd generation Intel Core processor family microarchitecture, codenamed Sandy Bridge, has generated such positive industry support,” said Zane Ball, general manager of the Desktop Products Division for Intel. “Suppliers such as ON Semiconductor are again ready to support the availability of the platform with industry leading voltage regulators. These components are important building blocks for next generation voltage regulation and can help lower overall system power consumption and improve energy efficiency.”
Controller / Driver Solution
The devices in ON Semiconductor’ new NCP61xx family of integrated controllers bring together the benefits of FlexMode™ and Dual-Edge pulse width modulation (PWM) to deliver the industry’s most efficient and highest performance controller solutions for VR12 and IMVP-7 designs. These new advanced devices include the NCP6151, NCP6121, NCP6131 and NCP6132. All offer user-configurable phase configuration and combine true differential voltage sensing, differential inductor DCR current sensing, input voltage feed-forward, and adaptive voltage positioning for accurately regulated power. Each device features a split current loop configuration that simplifies design-in by reducing tuning time and complexity, while Dual-Edge PWM combined with DCR current sensing delivers the fastest initial response to dynamic load events. The control loop’s non-linear transient response addresses the requirements of high-performance applications and a 30mV/sec slew rate, coupled with the feed-forward capability, minimizes charge and discharge times for high-efficiency operation. Efficiency is further enhanced through automatic ‘phase shedding’ to single-phase operation during light load operation.
Combining these NCP61xx controller ICs with ON Semiconductor’s new high-efficiency NCP5901 and NCP5911 MOSFET drivers – the industry’s smallest MOSFET drivers – creates a complete power delivery solution for both client and enterprise computing applications. (This combined controller and driver solution is priced at $2.79 per solution cost in 10,000 unit quantities.)
Power Delivery
ON Semiconductor’ new NTMFS49xx, NTTFS49xx, NTD49xx and NTMS49xx High Side Voltage Regulation (HSVR) MOSFETs are ideal for efficient computing power management. This family of 11 new high- efficiency MOSFETs uses advanced silicon technology optimized to provide the best switching performance in buck converter control-side applications. Each new device delivers very low gate charge (Qg) and gate resistance (Rg) to minimize switching losses and to improve signal quality; low capacitance to minimize driver losses; and low on resistance (RDS(ON)) to improve overall efficiency. (These HSVR MOSFETS will be available in SO8FL, u8FL, SOIC8, and DPAK/IPAK packages and priced at $0.20 to $0.35 per unit in 10,000 unit quantities.)
High Speed Switching
ON Semiconductor has also introduced the NS3L500 and NCN2612 as the first in a family of high speed switches targeting the high bandwidth, low power requirements of the computing interfaces that will be common to next generation computing platforms. These devices offer bandwidth sufficient to switch at the speeds demanded by Gigabit Ethernet, DisplayPort 1.2 and PCI Express 2.1, while reducing power by 80 percent compared to the competition. Ultra-low on-state resistance and capacitance minimize signal attenuation and ensure near zero propagation delay. (These devices are available in WQFN56 package for minimal board space consumption. The NS3L500 is priced at $2.00 per unit and the NCN2612 at $1.00 per unit in 1,000 unit quantities.)
Power Conversion
ON Semiconductor’s new NCP1910 high performance combo controller for ATX power supplies combines the power factor correction controller and main power stage controller of a Desktop PC power supply into a single IC solution. The device utilizes continuous conduction mode (CCM) power factor correction and a half-bride resonant LLC converter to enable high efficiency 80PLUS Gold/Platinum level efficiency designs. By combining the PFC and LLC controller into a single solution, the NCP1910 has integrated all the handshaking necessary for the two converters, increasing reliability and allowing for simpler, more compact designs. Designed for use in ATX, All-In-One, and server power supplies, the NCP1910 is available in a SOIC-24 package with budgetary pricing of $1.30 per unit in 10,000 unit quantities.
