DC/DC Converter
The PQ60018ETL45 PowerQor^® Tera eighth-brick converter
is a next-generation, board-mountable, 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 technology. Since
the PowerQor converter has no explicit thermal interfaces,
it is extremely reliable. RoHS Compliant (see page 14).
Operational Features
• High efficiency, 87% at full rated load current
• Delivers up to 45A of output current with minimal derating
- no heatsink required
• Wide input voltage range: 35-75V, with100V 100ms
input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement - no preload resistors required
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Open frame size: 0.90” x 2.3” (22.9x58.4mm)
• Total height only 0.320” (8.13mm) L-option, permits better
airflow and smaller card pitch
• Open frame total weight: 0.85oz (24g)
• Open frame units have flanged pins designed to
permit surface mount soldering (avoid wave solder)
using FPiP technique
PQ60018ETL45 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 converter from
external load induced pre-bias
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Safety Features
• 2250 V, 30 MΩ input-to-output isolation
• Certified to 60950-1 requirements for basic insulation
(see Standards and Qualifications page)
• RoHS compliant (see Page 14)
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
