A new 2-A source/sink converter targets DDR memory termination power in applications such as solid-state drives (SSDs), ultrabooks, servers, and embedded computing modules. The EV1320 VTT from Enpirion offers a peak efficiency of 96%, a 1.4-W power savings over a traditional low drop out (LDO) regulator-based solution in a comparable setting.
Available in a 3 mm ◊ 3 mm ◊ 0.55 mm QFN package, the device accepts an input voltage of 0.95 to 1.8 V and requires 80 mm2 of printed circuit board (PCB) area. The productís low profile allows mounting on the backside of the PCB, freeing up top-side board space. Users also can operate multiple devices for applications that use large complements of DDR memory. The EV1320 permits designers to reduce the memory subsystem's power dissipation in lieu of larger switching-regulator based memory termination options.
