The PowerQor Eighth-brick converter 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).

DC-DC Converter
Operational Features
High efficiency, 86% at full load
Delivers up to 20A of output current (50W) 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 resistors required
Mechanical Features
Industry standard eighth-brick pin-out configuration
Industry standard size: 0.90”x2.3” (22.9x58.4mm)
Total height only 0.320” (8.13mm), permits better airflow and
smaller card pitch
Total weight: 0.85oz. (24 grams)
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
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
