Dual Output, High Efficiency, Isolated DC/DC Converter
The DQ63312QGL07 DualQor^™ series is an indepen-
dently regulated dual output converter that uses the
industry standard quarter brick package size. The very
high efficiency is a result of SynQor’s patented topology
that uses synchronous rectification and an innovative
construction design to minimize heat dissipation and
allow extremely high power densities. The power dissi-
pated by the converter is so low that a heatsink is not
required, which saves cost, weight, height, and applica-
tion effort. All of the power and control components
are mounted to the multi-layer PCB substrate with high-
yield surface mount technology, resulting in a more reli-
able product.

DQ63312QGL07 Module
Operational Features
• Independently regulated outputs (separate control loops)
• High efficiency, 87% at full rated load current
• Delivers up to 68 Watts of output power with minimal
derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient withstand
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload resis-
tors required
Mechanical Features
• Industry standard pin-out configuration
• Industry standard size: 1.45” x 2.3”
• Low profile of only 0.34”, permits better airflow and
smaller card pitch
• Total weight: 1.1 oz (31 g), lower mass reduces
vibration and shock problems
Control Features
• On/Off control referenced to input side (positive
and negative logic options are available)
• Output voltage trim: +10%/-10%, permits custom
voltages and voltage margining

Protection Features
• Input under-voltage lockout disables converter at
low input voltage conditions
• Output current limit and short circuit protection
protects converter from excessive load current or
short circuits
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnor-
mal environmental conditions
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• UL/cUL 60950 recognized (US & Canada), basic
insulation rating
• TUV certified to EN60950
• Meets 72/23/EEC and 93/68/EEC directives
which facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flam-
mability requirements
