Intel Enpirion DC-DC Voltage Bus Converter



Intel Enpirion EC2650QI 12V DC-DC Step Down Voltage Bus Converter offers extremely high-efficiency, with integrated low ON-resistance MOSFET switches and small-signal control circuits in an advanced 5.5mm x 5.5mm x 0.9mm 36-pin QFN package. The EC2650QI Voltage Bus Converter features an output voltage that tracks one-half of the input voltage while powering the other Intel Enpirion 6V DC-DC converters.

The device offers a small size and enables a highly efficient 2-stage approach, allowing lower cost converters to be used without sacrificing total system efficiency. PCB board space can be greatly reduced when multiple rails are involved, allowing precious space needed for power regulation.

Intel Enpirion Power Solutions provides a significantly simplified board design, layout, and manufacturing requirements, implementing efficiency in system design and productivity. Additionally, overall system cost saving is enabled with a reduction in the number of components required for the complete power solution.
