EC2630QI PRODUCT BRIEF 12V DC-DC Intermediate Voltage Bus Converter, 27W and 4A Description Features The Enpirion EC2630QI is a high density DC-DC Complete power conditioning solution from a Intermediate Voltage Bus Converter which 12 volt power bus. generates a highly efficient output voltage. Wide system input voltage range of 6V to EC2630QI tracks one half the input voltage and 13.6V. is designed to work with Enpirions highly High and flat efficiency, up to 97.5%. integrated DC to DC point-of-load converter 4A Continuous Output Current Capability products for a complete 12V solution. EC2630QI Adjustable operating frequency with optional provides the means to condition power from a external clock input. 12V input, to supply multiple lower voltage Master/Slave Mode for Parallel Operation converters while enabling high efficiency and Load-based dynamic clock scaling small PCB area. Due to its extremely high Output Enable pin, VoutOK, VinOK efficiency, it avoids the common two stage power Pre-programmed soft-start time. conversion penalty and is equivalent or better Thermal shutdown, short circuit, Overload, than direct regulation. OVLO and UVLO protection. RoHS compliant, MSL level 3, 260C reflow. This Enpirion solution significantly helps in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements. In addition, a reduction in the number of vendors required for the complete power solution helps to enable an Application overall system cost savings. All Enpirion Applications requiring down converting from a products are RoHS compliant and use a lead- 12V bus to a well regulated output voltage free manufacturing environment. with high efficiency, in a compact foot print (Note: The total system application involves two or more Enpirion products.) Enterprise, Industrial, Embedded, and Telecommunication applications Multi-rail compute & network interface applications such as PCIe and ATCA AMC cards. 12V Industrial and Consumer Applications such as Audio/Video Home Theater, Tuners 2 Figure 1: ~140mm solution footprint with low package profile permitting back side PCB mounting. www.enpirion.com EC2630QI Application Schematic Pin Assignments (Top View) EC2630QI VOUT V IN VOUT PVIN CFLYP ENA 47 F 22F 3x 47 F ** AVIN 1206 1206 3x 1206 PGND CFLYN 0.1 F VBOOT V3P3 PGND AGND FADJ 0.1 F 100 k ** 1-2 of Cout can be eliminated due to downstream input bypass capacitance (e.g. PoL converters).
