Increasing the number and capacity of memory modules in enterprise products such as servers is creating the need for high-efficiency voltage termination (VTT) solutions to minimize power loss. This needs to be achieved within a smaller PCB footprint, while still meeting the DDR2/DDR3/DDR4 requirements for tracking accuracy and AC + DC regulation.
The Intel® Enpirion® EV1340QI 5A high-efficiency memory termination voltage step-down converter, designed for VTT applications, provides an excellent combination of solution size and efficiency. This switch-mode DC-DC converter is a complete power system on a chip (PowerSoC), integrating the inductor, power switches, gate drive, controller, and loop compensation in a tiny 5.5 mm x 10.0 mm x 3.0 mm QFN package. The EV1340QI also offers 91% efficiency.
With the power requirements increasing on the VTT rail, it is especially critical to use DC-DC converters that offer the best combination of solution size and efficiency. The EV1340QI helps to dramatically reduce power loss without sacrificing PCB area.
