Dualeta™ iQA Series DC/DC Power Modules
The Dualeta™ Family is a 75W family of highly versatile,
independently regulated, dual output quarter brick
power modules with output voltage tracking. Its output
current loading scheme is fully flexible: 0 to 15A can be
drawn from either output with no minimum load
requirements. An ultra wide range independent output
trim allows the realization of dual output voltage
combinations between 1.5 and 5.5V. The superior
versatility of the Dualeta™ family substantially reduces
the quantity of distinct part numbers in the end user part
portfolio, lowering cost of ownership.
Monotonic, tracking start-up
Starts with pre-biased outputs
High reliability open frame, surface
mount construction
Baseplate for improved thermal
management
UL 60950 (US and Canada), VDE 0805,
CB scheme (IEC950)
Patented Technology
Options
Optional Single Tracking Trim – using
industry standard resistor tables
Remote on/off (negative logic)
Short Thru-hole pins 2.79 mm (0.110")
(877) 498-0099
48V Input, 15A Output
