The PowerQor^® Eighth-brick series is composed of next
generation, board-mountable, isolated, fixed switching
frequency dc/dc converters that use synchronous
rectification to achieve extremely high power 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 technology. Since the PowerQor converter has
no explicit thermal interfaces, it is extremely reliable.
RoHS Compliant (See page 15).
2000Vdc
Isolation
Eighth-brick
DC-DC Converter
Operational Features
• High efficiency, 87% at full rated load current
• Delivers up to 48W of output power with minimal derating -
no heatsink required
• Operating input voltage range: 35V-75Vdc, 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 eighth-brick pin-out configuration
• Size: 0.9” x 2.3” (22.9 x 58.4mm)
• Low Profile total height only 0.340” (8.64mm), permits better airflow
and smaller card pitch
• Total weight: 0.85oz (24g)
• Flanged pins designed to permit surface mount soldering (avoid wave
solder) using FPiP technique
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 converter from external load
induced pre-bias
• Output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions

Module
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
Safety Features
• 2000V, 30MΩ input-to-output isolation provides input/output
ground separation
• UL 60950-1 recognized (US & Canada),basic insulation rating
• TUV certified to EN60950-1
• Board and plastic components meet UL94V-0 flammability requirements
