1. DESCRIPTION

The EN6347QI is an Intel® Enpirion® Power System on a Chip (PowerSoC) DC-DC converter. It integrates the inductor, MOSFET switches, small-signal circuits and compensation in an advanced 4mm x 7mm x 1.85mm 38-pin QFN package. The EN6347QI is specifically designed to meet the precise voltage and fast transient requirements of present and future high-performance, low-power processor, DSP, FPGA, memory boards and system level applications in distributed power architectures. The device’s advanced circuit techniques, high switching frequency, and proprietary integrated inductor technology deliver high-quality, ultra compact, non-isolated DC-DC conversion. Intel Enpirion Power Solutions significantly help in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements. In addition, a reduction in the number of components required for the complete power solution helps to enable an overall system cost saving. All Enpirion products are RoHS compliant and leadfree manufacturing environment compatible.
