Enpirion Power Datasheet EN5396QI 9A PowerSoC Synchronous DC-DC Buck Converter with Integrated Inductor Features Description The EN5396QI is a Power Supply on a Chip (PwrSoC) DC-DC converter. It is specifically designed to meet the precise voltage and fast transient requirements of present and future 10mm high-performance, low-power processor, DSP, FPGA, ASIC, memory boards, and system level applications in a distributed power architecture. Advanced circuit techniques, ultra high switching 12mm frequency, and innovative, high-density, Integrated Inductor Technology: Integrated integrated circuit and proprietary inductor Inductor, MOSFETS, Controller in a 10 x 12 x technology deliver high-quality, ultra compact, non-isolated DC-DC conversion. Operating this 1.85mm package converter requires as few as five external Low External Part Count. components that include small value input and Up to 30W continuous output power. output ceramic capacitors and a soft-start Low output impedance optimized for 90 nm capacitor. Master/slave configuration for paralleling. 5MHz operating frequency. The Altera Enpirion solution significantly helps in High efficiency, up to 93%. system design and productivity by offering greatly Wide input voltage range of 2.375V to 5.5V. simplified board design, layout and External resistor divider output voltage select. manufacturing requirements. In addition, a Output Enable pin and Power OK signal. reduction in the number of vendors required for Programmable soft-start time. the complete power solution helps to enable an Adjustable over-current protection. overall system cost savings.
