CHiL Digital Controllers Highlighted in Newly Launched Sandy Bridge-based Performance Motherboards
Digital control solution offers performance, reliability, energy and environmental savings
Tewksbury, MA (PRWEB) January 14, 2011
CHiL Semiconductor Corporation, a leading developer of high-performance, mixed-signal power management integrated circuits for the server, personal computer and high-volume computing market segments, announces that its digital controllers are highlighted in motherboards containing Intel’s newly launched P67 “Sandy Bridge”-based performance motherboards from Asus, Intel and ASRock.
The new motherboards reflect the CPU voltage regulator’s (VR’s) key role in both performance and energy savings. The customized power solution showcases performance in overclocking, stability, and features, while at the same time providing exceptional power efficiency. CHiL’s well proven digital power management is at the core of the power solution.
The CHiL VR solutions are found in ASUS high end motherboards, overclocking gaming motherboards, and workstations like the Maximus 4 Extreme and the P8P67. They are also in Intel motherboards like the Intel DP67BG (Burrage) Extreme Series, manufactured by Mitac and the BA 3+0, manufactured by Pegatron, as well as ASRock’s high end motherboards, P67 Extreme 4 and P67 Extreme 6.
Voltage regulator modules are considered among the most essential motherboard design components. According to ASUS, the use of the new digital power design empowers users with superior flexibility and perfect precision to ensure optimized performance, extreme system stability and greater power efficiency.
Anandtech, a leading industry source for hardware analysis and news, notes that these new motherboards have lower power consumption than virtually any other available platform under load.
“The introduction of Intel’s Sandy Bridge processor family brings brand new power requirements to the VR industry,” said CHiL chief executive officer Ram Sudireddy. “These requirements, known as VR12, implement a new, highly digital communication SVID bus between the CPU and the VR in order to optimize efficiency and performance. Implementing this highly digital content means that an all-digital VR solution is definitely the best choice.”
The CHiL VR is extremely efficient, which is of greater concern than ever in the marketplace. When high power use is not needed, many of the phases can be turned off. Unlike analog solutions, which have difficulty maintaining a stable voltage with some or most of the phases disabled, the new digital VR ensures that under any voltage and current, with any version of the Sandy Bridge CPU, the optimum number of phases is chosen, while the voltage is always guaranteed to be stable. At very low power levels, the VR’s digital algorithm automatically senses that power is low and places the VR into a very low power state, called discontinuous mode, which saves even more power, so the user saves power in idle state as well.
The system’s telemetry reports back all critical information to the system with extremely high accuracy, including voltage, current, power and temperature. The VR can change switching frequency on the fly, to reduce system noise and help with efficiency. When the voltage is changed significantly, or the current increased significantly in an overclocking board, the digital solution’s stability parameters can simply be changed, something impossible with an analog solution.
The CHiL VR also features new circuit protection features. As the voltage changes in overclocking, or as the current increases, overcurrent protection and voltage protection set points can be updated in real time, ensuring the circuit is always protected.
With the P67 family of processors comes a new way to achieve overclocking. The VR solution extends the Sandy Bridge voltage range to reach higher voltage levels with extreme accuracy, stability and voltage and current protection, all managed by CHiL’s digital engine. The VR also allows the motherboard to remain in turbo-mode safely, protecting the CPU with exceptional thermal performance, allowing a much richer, but safe overclocking experience.
The all-digital VR is also extremely reliable. Analysis using Mil-HDBK-217F, a military quality technique for determining reliability, showed that the digital VR is two times less likely to fail than an analog solution, primarily because the digital solution uses far fewer external components and pins than an analog solution.
The new CHiL VR has a uniquely engineered spread spectrum technique, where the VR switching frequency is changed as it operates, reducing board level noise, ensuring safe, low noise operation.
Besides saving energy, the CHiL VR uses fewer external components and comes in a smaller, fully RoHS-compliant package, thus reducing the number of electronic parts that may someday require disposal in a landfill.
