DDR - Double Data Rate Random Access Memory Memory and 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. Applications That Help Power Supply Designers Meet Global Efficiency Requirements PHOENIX -- ON Semiconductor (Nasdaq: ONNN), a global supplier of efficient power management solutions, has expanded its computing products portfolio with the introduction of three new power controllers, specifically designed to meet the efficiency requirements of notebook PCs. The NCP (1) (Network Control Program) See SNA and network control program. (2) (NetWare Core Protocol) The file sharing protocol used in a NetWare network. 5371, NCP5218, and NCP5215 controllers address the notebook power subsystem needs for Vcore, DDR memory, and CPU chipsets respectively. These devices join the recently introduced NCP5387 and NCP5382 dual-edge Vcore control solutions for desktop PCs and servers that ON Semiconductor designed to enable more efficient and more compact power solutions for computing applications. "During the past 18 months, ON Semiconductor has expanded its computing portfolio and design-wins with 12 new Vcore and system controllers for desktop motherboard manufacturers, the introduction of Vcore and power controllers for notebooks, and 18 new Trench FETs specifically designed for computing applications," said Bill Schromm, senior vice president and general manager of ON Semiconductor's Computing Products Group. "We now provide a total power solution for a broad range of computing systems. "In addition to controllers and MOSFETs, ON Semiconductor supplies a full range of the semiconductor components essential to power system design - such as regulators, rectifiers, transistors and diodes," said Schromm. "Our comprehensive product offering, backed by our technical expertise, offers customers the advantage of working with a single supplier to design complete computing power subsystem solutions. Later this year, we plan to introduce additional power controllers and MOSFETs designed to meet our customers' evolving power management needs and to provide them with innovative options for efficient power management designs." The Devices Featuring a variety of power-saving features, the new controllers improve the efficiency of power management subsystems in notebook computers A laptop computer that weighs in a range from five to seven pounds. The term originated when laptops were routinely more than 10 pounds, and those that became lighter were placed in a special "notebook" category. In practice, notebook computer and laptop computer are synonymous. by up to 5 percent, thereby extending battery life. The memory and chipset controllers operate with fewer capacitors than existing solutions, enabling physically smaller power management subsystems and leaving more circuit board real estate available for other functions. The NCP5371 is a 2-phase, dual-edge Vcore controller, specifically designed to support notebook mobile processor power delivery requirements The stipulation that requires that an item of materiel must be delivered in the total quantity required by the date required. .

Automatic variable frequency operation during light load conditions provides high subsystem efficiency and fast transient response In electrical engineering and Mechanical Engineering, a transient response or natural response is the response of a system to a change from equilibrium. Specifically, transient response in Mechanical Engineering is the portion of the response that approaches zero after a out of light load operation. The device includes gate drivers that are optimized for large Qg low-side MOSFETs, further improving overall subsystem efficiency. The NCP5371 is available in a Pb-free QFN-48 package, and is priced at $3.33 per unit in 2,500 unit quantities. The NCP5218 is a 2-in-1 power controller, specifically designed as a total solution for notebook DDR memory subsystems. This device combines the efficiency of a 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 for the VDDQ supply, with the simplicity of a linear regulator In electronics, a linear regulator is a voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its "linear region" (in contrast, a switching regulator is based on a transistor forced to act as an for the VTT VTT Technical Research Centre of Finland VTT Valtion Teknillinen Tutkimuskeskus (Finnish: Technical Research Centre of Finland) VTT Vélo Tout Terrain (French: mountain bike; aka ATB or MTB) supply. The high bandwidth VTT regulator requires only a 20 microfarad See Farad. ceramic output capacitor, versus the 60 microfarad of capacitance capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. required for existing market solutions, saving board space and cost. A power saving mode for light load conditions improves subsystem efficiency. The inclusion of VDDQ power good voltage monitoring, VDDQ overcurrent, overvoltage, and undervoltage protection, supply undervoltage monitoring, soft[?]start, and thermal shutdown makes this device a total power solution for high current DDR memory subsystems. The NCP5218 is available in a Pb-free DFN-22 package, and is priced at $1.13 per unit in 2,500 unit quantities. The NCP5215 is a dual-channel buck controller, specifically designed for notebook chipsets. A programmable power-saving mode delivers high efficiency of greater than 90 percent over the entire load range. The 180[deg] interleaved operation reduces input capacitance requirements, while the programmable Adaptive Voltage Position reduces output capacitance requirements, combining to reduce board space for capacitors by 25 percent versus existing solutions. The NCP5215 is available in a Pb-free QFN-40 package, and is priced at $1.13 per unit in 2,500 unit quantities.
