Data Sheet: Dualeta™ iQA Series – Dual Quarter Brick

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.

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:

o Standard Dual Trim – wide range

independent adjustment of either output, using two trim pins

o Optional 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:

o Input under and over voltage o Output over voltage o Current limit o Short circuit o Thermal 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”)
