Technical Specification
48Vin 3.3/1.8Vout 77W
Quarter
Brick Dual
The DQ63318QGL08 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, High Efficiency, Isolated DC/DC Converter
DQ63318QGL08 Module
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
Safety Features
2000V, 30 M
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
Operational Features
Independently regulated outputs (separate control loops)
High efficiency, >87% at full rated load current
Delivers up to 77 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
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
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.
