Enpirion’s latest converter offers alternative to traditional DDR power solutions

The EV1320 VTT converter accepts an input voltage of 0.95 to 1.8V. 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. For example, 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.

“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.”

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.of an LDO.
