New converter offers cost effective alternative to traditional DDR power solutions
The device is targeting a wide range of applications including ultrabooks, servers, solid state drives (SSDs) and embedded computing modules.
The EV1320 VTT converter accepts an input voltage of 0.95 to 1.8 V. The device is available in a 3 mm x 3 mm x 0.55 mm tall QFN package and requires only 80 mm2 printed circuit board (PCB) area for the total solution. Multiple devices can also be operated in parallel to provide a high-efficiency, cost- and footprint-effective solution for applications that use large complements of DDR memory.
The power savings in a typical 2P server is more than 11 Watts. With 10 million new servers deployed annually, this equates to over 110 million Watts of energy savings and associated cooling costs just for server applications – without incurring additional hardware costs. Considering other targeted applications such as PCs, notebooks, tablets and embedded computing could result in 450 million Watts of additional potential power savings.
EV1320 is a purpose-built VTT converter solution that complies with JEDEC specifications for supporting DDR2/DDR3/QDR and low-power DDR3/DDR4 VTT applications.
The EV1320 and Enpirion’s entirePowerSoC portfolio claims to provide the industry’s highest-density power solutions and minimizes the amount of space needed for power management. The EV1320’s low profile enables mounting on the backside of PCBs, freeing up precious top-side board space.
Enpirion power management solutions achieve 21,800 years mean time between failure (MTBF). Enpirion high-efficiency devices are truly industrial graded and do not require load de-rating at 85 °C ambient temperature. PowerSoCs are specified, simulated, characterized, validated and manufacturing-tested as a complete power system –which, when coupled with tightly controlled IC manufacturing processes and fewer total components, yields unsurpassed reliability.
The EV1320 claims to provide the performance of a switching regulator at a cost point of an LDO.
“Every generation of electronics products adds new features, functions and compute resources, which in turn drives an increase in DDR memory capacity to the point where the memory termination power is becoming significant,” said Mark Cieri, Enpirion’s director, business development and marketing. “The EV1320 enables designers to significantly reduce the memory subsystem’s power dissipation without resorting to more expensive, larger switching regulator-based memory termination options.”
Availability and Pricing
Enpirion’s EV1320 device is sampling now, with volume production by February 2012. It is available direct from Enpirion or through distribution for $0.70 at volumes of 1k units.
