DataSheeT enpirion power solutions EN5395QI 9A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION NOT RECOMMENDED FOR NEW DESIGN The EN5395QI is a Power System on a Chip FEATURES (PowerSoC) DC-DC converter. It is specifically designed to meet the precise voltage and fast transient requirements of present and future high- performance, low-power processor, DSP, FPGA, ASIC, memory boards, and system level applications in 10mm distributed power architecture. Advanced circuit techniques, ultra-high switching frequency, and innovative, high-density, integrated circuit and proprietary inductor technology deliver high-quality, 12mm ultra-compact, non-isolated DC-DC conversion. Integrated Inductor Technology: Integrated Operating this converter requires as few as five Inductor, MOSFETS, Controller in a 10 x 12 x external components that include small value input 1.85mm package and output ceramic capacitors and a soft-start Low Part Count: only 5 MLC Capacitors. capacitor. Up to 30W continuous output power. Intel Enpirion solution significantly helps in system Low output impedance optimized for 90 nm design and productivity by offering greatly simplified Master/slave configuration for paralleling. board design, layout and manufacturing 5MHz operating frequency. requirements. In addition, a reduction in the number High efficiency, up to 93%. of vendors required for the complete power solution Wide input voltage range of 2.375V to 5.5V. helps to enable an overall system cost savings. 3-Pin VID output voltage select to choose one of 7 pre-programmed output voltages.
