EN5394QI中文资料9A PowerSoC Voltage Mode Synchronous Buck PWM DC-DC Converter With Integrated Inductor数据手册Intel规格书

描述 Description

The EN5394QI is a Power Supply on a Chip (PwrSoC) DC to DC converter with integrated inductor, PWM controller, MOSFETS, and compensation providing the smallest possible solution size in a 68 pin QFN module. The switching frequency can be synchronized to an external clock or other EN5394QIs with the added capability of phasing multiple EN5394QIs as desired. Other features include precision ENABLE threshold, pre-bias monotonic start-up, margining, and parallel operation.
EN5394QI is specifically designed to meet the precise voltage and fast transient requirements of present and future high-performance applications such as set-top boxes/HD DVRs, LAN/SAN adapter cards, audio/video equipment, optical networking, multi-function printers, test and measurement, embedded computing, storage, and servers. Advanced circuit techniques, ultra high switching frequency, and very advanced, high-density, integrated circuit and proprietary inductor technology deliver high quality, ultra compact, non-isolated DC-DC conversion. Operating this converter requires very few external components.
The Altera Enpirion integrated inductor solution significantly helps to reduce noise. The complete power converter solution enhances productivity by offering greatly simplified board design, layout and manufacturing requirements.
All Altera Enpirion products are RoHS compliant and lead-free manufacturing environment compatible.
