Technical Specification *
Quarter
Brick
48Vin 18Vout 5.6A
100 Watt, No Heatsink, Isolated DC/DC Converter
The PQ65180QGA06 PowerQor^™ Giga quarter-
brick converter is a next-generation, board-mount-
able, isolated, fixed switching frequency DC/DC
converter that uses synchronous rectification to
achieve extremely high conversion efficiency. The
power dissipated by the converter is so low that a
heatsink is not required, which saves cost, weight,
height, and application effort. All of the power and
control components are mounted to the multi-layer
PCB substrate with high-yield surface mount tech-
nology. Since the PowerQor converter has no
explicit thermal interfaces, it is extremely reliable.
Operational Features
• Ultra-high efficiency, 91% at full rated load current
• Delivers up to 100 Watts of output power with mini-
mal derating - no heatsink required
• Wide input voltage range: 40V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.40” (10.2mm), permits better
airflow and smaller card pitch
• Total weight: 1.2 oz. (34 grams)
• Flanged pins designed to permit surface mount sol-
dering (avoid wave solder) using FPiP technique
Control Features
• On/Off control referenced to input side (positive
and negative logic options are available)
• Remote sense for the output voltage compensates
for output distribution drops
• Output voltage trim 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 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
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
* Final datasheet pending ECO review and signature.
