Datasheet - enpirion power solutions EC2650QI 6A Voltage Divider High Efficiency 12V to 6V (33W) Intermediate Bus Converter DESCRIPTION FEATURES The EC2650QI is an Intel Enpirion DC-DC High Efficiency (Up to 94%) intermediate voltage bus converter with extremely Very Thin 12V to 6V Converter Solution high efficiency. It integrates low ON-resistance 2 150mm Optimized Total Solution Size MOSFET switches and small-signal control circuits in 5.5mm x 5.5mm x 0.9mm Package an advanced 5.5mm x 5.5mm x 0.9mm 36-pin QFN 8V to 13.2V Input Voltage Range package. Up to 6A Continuous Operating Current The EC2650QI generates an output voltage that Adjustable Switching Frequency tracks one-half of the input voltage and is designed to power the other Intel Enpirion 6V DC-DC Master/Slave Parallel Operation (up to 144W) converters. By using a highly efficient 2-stage Input Power OK Indicator approach with the EC2650QI, smaller size and lower Over-Current, Short Circuit, Thermal Shutdown, cost converters may be used without sacrificing total Input OVP and UVLO Protection system efficiency. When multiple rails are involved, RoHS Compliant, MSL Level 3, 260C Reflow this can greatly reduce precious PCB board space needed for power regulation. APPLICATIONS Intel Enpirion Power Solutions significantly help in 12V Applications Requiring High Efficiency, Small system design and productivity by offering greatly Solution Size and High Power Density simplified board design, layout and manufacturing Systems with FPGA, ASICs, or ASSPs that Require requirements. In addition, a reduction in the number Multiple Power Rails of components required for the complete power Applications with Multiple Power Rails such as solution helps to enable an overall system cost Industrial, Networking, embedded Computing and saving. PCIe Cards All Enpirion products are RoHS compliant and lead- 12V Industrial and Consumer Applications in free manufacturing environment compatible.
