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”)
