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 connections, it is extremely reliable.
Operational Features
• Ultra-high efficiency, 89% at full rated load current
• Delivers up to 100 Watts of output power with minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V meets or exceeds all 48V bus standards
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors 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 abnormal environmental conditions
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3”
• Total height less than 0.40”, permits better airflow and smaller card pitch
• Total weight: 34 grams (1.2 oz.), lower mass greatly reduces vibration and shock problems
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, 10 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
