Dualeta™ iQA Series DC/DC Power Modules
48V Input, 15A Output
Dual Output Quarter Brick
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.
Features
•Standard Dual Quarter Brick format
•A single module which can support
all your dual voltage requirements
between 1.5V and 5.5V
•Two output trim options:
oStandard Dual Trim – wide range
independent adjustment of either
output, using two trim pins
oOptional Single Tracking Trim –
adjust both outputs together by 10%
according to industry standard
resistor tables
•Independently regulated, tight
tolerance outputs
•Flexible loading: 0-15A from either
output, 15A total load
•High efficiency – up to 89%
•Industry-leading output power: 75W
•Basic insulation – 1500 Vdc
•Full, auto-recovery protection:
oInput under and over voltage
oOutput over voltage
oCurrent limit
oShort circuit
oThermal limit
•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”)
