ON Semiconductor’s Advanced Controller To Drive Upcoming
Eighth-Generation AMD Athlon™ Processor-based
Platforms for Desktop Computing
Two-phase PWM controller, with integrated gate drivers, delivers fast transient response and excellent overall power regulation while reducing space and saving costs
PHOENIX, Ariz. --
ON Semiconductor (Nasdaq: ONNN) today announced that it is working with AMD to provide innovative power management devices for the upcoming eighth-generation AMD Athlon™ processors. Utilized in combination, ON Semiconductor’s NCP5331 advanced multiphase controller and fast-switching, low RDS(on) power MOSFETs, provide a highly reliable and cost effective power management solution for AMD’s forthcoming processors based on x86-64 architecture.
“ON Semiconductor has worked closely with AMD throughout the development of our NCP5331 multiphase controller to ensure it meets the demanding power delivery specifications for the next-generation AMD Athlon processors,” said Jim Alvernaz, ON Semiconductor computer products group director. “Samples of the NCP5331 are available now - so engineers designing desktop computing systems can implement efficient Vcore
power supply designs immediately.”
“ Targeting the high-performance, advanced computing 64-bit market, AMD and ON Semiconductor technologies can help provide the power, reliability and stability our shared customers require,” said Rich Heye, vice president, platform engineering and infrastructure, Computation Products Group, AMD. “For systems based on the upcoming eighth-generation AMD processors, customers can also experience optimized 32-bit application and system performance and migrate to a 64-bit environment as needed.”
The NCP5331 is a two-phase Pulse Width Modulation (PWM) controller with integrated gate drivers. By its design, the NCP5331 simplifies power supply implementation while increasing reliability and expanding design flexibility. Delivering a solution size that is smaller than competitive offerings, the NCP5331 is housed in a 7mm x 7mm 32-lead QFN package that effectively conserves board space.
ON Semiconductor’s Enhanced V2
™ control method provides fast transient response (100 nanoseconds) and reduced jitter thus minimizing the number of output capacitors required. The output voltage is set by a highly accurate 5-bit Digital to Analog Converter (DAC) - which is programmable from 0.8V to 1.55V. The NCP5331 seamlessly supports the requirement for voltage ID (VID) shift on the fly, allowing the processor to change the output voltage of the controller without creating any out-of-spec glitches. A programmable over-current shutdown timer limits hiccup time and prevents potential damage to MOSFET switches.
To support the NCP5331 application with the upcoming eigth-generation AMDAthlon processor, ON Semiconductor recommends two Power MOSFETs – the 60Amp/28V NTD60N03 switch for the high side and the 80Amp/24V NTD80N02 switch on the low side. The NTD60N03 device is optimized for fast switching while the NTD80N02 is optimized for lowest possible Rds(on). Together these characteristics help to maximize system efficiency. Evaluation boards and reference designs are available to assist and simplify design-ins.
