DataSheeT enpirion power solutions EN6310QI 1A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN6310QI is an Intel Enpirion Power System on Integrated inductor, MOSFET and Controller a Chip (PowerSoC) DC-DC converter. It integrates the Small 4mm x 5mm x 1.85mm QFN inductor, MOSFET switches, small-signal circuits and High Efficiency up to 96% compensation in an advanced 4mm x 5mm x 1.85mm 2 30-pin QFN package. Solution Footprint Less than 65mm 1A Continuous Output Current The EN6310QI is specifically designed to meet the VIN Range of 2.7V to 5.5V precise voltage and fast transient requirements of present and future high-performance, low-power VOUT Range from 0.6V to 3.3V processor, DSP, FPGA, memory boards and system Programmable Soft Start and Power OK Flag level applications in distributed power architectures. Fast Transient Response and Recovery Time The devices advanced circuit techniques, high Low Noise and Low Output Ripple 4mV Typical switching frequency, and proprietary integrated 2.2MHz Switching Frequency inductor technology deliver high-quality, ultra compact, non-isolated DC-DC conversion. Under Voltage Lock-out (UVLO), Short Circuit, Over Current and Thermal Protection Intel Enpirion Power Solutions significantly help in system design and productivity by offering greatly APPLICATIONS simplified board design, layout and manufacturing requirements. In addition, a reduction in the number Altera FPGAs (MAX, ARRIA, CYCLONE, STRATIX) of components required for the complete power Low Power FPGA Applications solution helps to enable an overall system cost All SERDES and IO Supplies Requiring Low Noise saving. Applications Requiring High Efficiency All Enpirion products are RoHS compliant and lead- Enterprise Grade Solid State Drive (SSD) free manufacturing environment compatible.
