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
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
• 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)
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
