DataSheeT enpirion power solutions EV1380QI 8A PowerSoC TM Highly Integrated Synchronous DC-DC DDRxQDR Memory Termination DESCRIPTION FEATURES High efficiency, up to 94%. The EV1380QI is a Power System on a Chip Output voltage tracks VDDQ +/- 1% (PowerSoC) DC-DC converter in a 68 pin QFN that is optimized for DDR2, DDR3, and QDRTM VTT Nominal 1.5MHz operating frequency with ability applications. It requires a power supply (AVIN) for the to synchronize to an external clock source or controller and operates from an input supply (VDDQ). serve as the primary source. It provides a tightly regulated and very stable output Programmable soft-start time. Soft Shutdown. voltage (VTT) which tracks VDDQ while sinking and Master/slave configuration for parallel operation. sourcing up to 8A of output current. Intel Enpirions Thermal shutdown, over current, short circuit, integrated inductor technology significantly helps to and under-voltage protection. reduce noise, and offers a high efficiency solution for RoHS compliant, MSL level 3, 260C reflow. VTT applications with a very low external component count. APPLICATIONS Advanced circuit techniques, optimized switching Bus Termination: DDR2, DDR3, DDR4 & QDR frequency, and very advanced, high-density, memory integrated circuit and proprietary inductor technology deliver high-quality, ultra compact, non- isolated DC-DC conversion. The complete power converter solution enhances productivity by offering greatly simplified board design, layout and manufacturing requirements.
