Technical Specification
Brick Dual
48Vin 5.0/3.3Vout 100W
Quarter
Dual Output, High Efficiency, Isolated DC/DC Converter
The DQ65033QGL10 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.
Dual Output
Operational Features
• Independently regulated outputs
(separate control loops)
• High efficiency, 88% at full rated load current
• Delivers up to 100 Watts of output power with minimal
derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload resis-
tors required
DQ65033QGL10 Module
Protection Features
• Input under-voltage lockout disables converter at
low input voltage conditions
• Output current limit and short circuit protection
protects converter and load from permanent damage
and consequent hazardous conditions
• Active back bias limit prevents damage to convert-
er from external load induced pre-bias
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnor-
mal environmental conditions
Mechanical Features
• Industry standard pin-out configuration
• Industry standard size: 1.45” x 2.3”
(36.8x58.4mm)
• Low profile of only 0.34”
(8.64mm),
permits better
airflow and smaller card pitch
• Total weight: 1.1 oz
(31 g),
lower mass reduces
vibration and shock problems
• Flanged pins designed to permit surface mount sol-
dering (avoid wave solder) using FPiP technique
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
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. Optional sec-
ond trim pin allows independent trimming.

NOTES
1) All pins are 0.040” (1.02mm) diameter with
0.080” (2.03 mm) diameter standoff shoulders.
2) Other pin extension lengths available. Recommended pin
length is 0.03” (0.76mm) greater than the PCB thickness.
3) All Pins: Material - Copper Alloy
Finish - Tin/Lead over Nickel plate
4) Undimensioned components are shown for visual
reference only.
5) All dimensions in inches (mm)
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
6) Weight: 1.1 oz. (31 g) typical
7) Workmanship: Meets or exceeds IPC-A-610C Class II
8) Modules can be ordered as QGA option that have different
pins to provide a minimum bottom side clearance of
0.076” while increasing maximum height to 0.424”.
See ordering page for more information.
9) The flanged pins are designed to permit surface mount
soldeing (avoiding the wave soldering process) through
the use of the flanged pin-in-paste technique.

NOTES
1. For Standard feature unit (S feature), one trim pin (pin 6) trims both outputs
simultaneously by the same amount in the same direction.
2. For units with optional trim pin (T feature), the original trim pin (pin 6)
trims the low voltage output and the optional trim pin (pin A) trims the high
voltage output. Both trim independently of one other.
