Enpirion^® Power Datasheet
EC2630QI 4.5A, 27W 12V DC-DC
Intermediate Voltage Bus Converter
Description
Altera’s Enpirion EC2630QI is a high density
DC-DC Intermediate Voltage Bus Converter
which generates a highly efficient output
voltage. EC2630QI that tracks one half the
input voltage and is designed to work with
Altera’s highly integrated Enpirion DC to DC
point-of-load converter products for a complete
12V solution. EC2630QI provides the means
to condition power from a 12V input, to supply
multiple lower voltage converters while
enabling high efficiency and small PCB area.
Due to its extremely high efficiency, it avoids
the common two stage power conversion
penalty and is equivalent or better than direct
regulation.
This Altera 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
overall system cost savings. All of Altera’s
Enpirion products are RoHS compliant and use
a lead-free manufacturing environment.
