Voltage Regulator Modules meet AMD power specifications.
Press Release Summary:
Achieving greater than 85% efficiency, Models VRK81B080CS and VRK81B080CU are 80 A, 2U and 1U high, respectively, while 100 A Model VRK81B100TH is horizontally mounted and measures 0.415 in. high. Units feature 12 V nominal input and 0.8-1.55 V output voltage, which is VID programmable, allowing processor to command exact voltage required. Modules are RoHS compliant and meet specifications for powering AMD Opteron(TM) processors, which target compute-intensive applications.
Original Press Release:
High Efficiency VRMs Meet AMD K8 Processor Power Specifications
o >85% efficiency eases system design
o 1U/2U or horizontal mounting for workstation or server-room applications
o Meets AMD power specifications to satisfy latest 64-bit AMD Opteron(TM) and Athlon(TM) processor families
February 10th, 2006, Mansfield, MA - C&D Technologies (NYSE: CHP) has launched a new series of voltage regulator modules (VRMs) that have high efficiency, high current density and fast transient load response meeting the AMD64(TM) processor power specifications.
The 80A VRK81B080CS and VRK81B080CU are 2U and 1U high units respectively. A third regulator module, the 100A VRK81B100TH, is horizontally mounted and measures just 0.415" high to enable extremely low profile implementation. These three options provide designers with a high degree of flexibility to match diverse system requirements from workstation to server-room applications. All three modules achieve greater than 85% efficiency, which eases system design by allowing lower component temperatures and simplifies system thermal management by reducing power dissipation.
The new modules are all fully RoHS compliant, and meet the strict specifications for powering the latest AMD Opteron(TM) processors, which target compute-intensive applications including professional digital media. The regulator specification is tight, to meet the processor's demands when performing computationally intensive tasks such as financial modeling, scientific applications, CAD graphics, or intensive database transactions. VRMs for use with Opteron processors must satisfy fast load transients demanding up to 100A/µs, and must provide a variety of integrated monitoring and protection features such as power good indicator, overcurrent latch-off, short circuit protector, differential remote sense and tri-state output when disabled. The VRK81B080CS and VRK81B080CU also offer support for an I²C temperature monitor, allowing applications that use the System Monitoring Bus (SMBus) to add further load-related controls such as variable fan speed.
Input and output ratings for the VRK81B080CS, VRK81B080CU and VRK81B100TH are 0.8V-1.55V-output voltage, and 12V nominal input voltage. The output voltage is VID programmable allowing the processor to command the exact voltage required.
"Developing VRMs already proven to meet popular processor power specifications helps simplify the task of designing for engineers," said Rob Hill, Vice President of Global Product Development C&D Technologies. "The high efficiency levels and small form factor of the VRK81B080CS, VRK81B080CU and VRK81B100TH also brings other important benefits to customer's product designs."
Pricing in OEM quantities is $28.80 per unit for the VRK81B080CS and VRK81B080CU, and $36.30 per unit for the VRK81B100TH.
