PQ60018ETx45数据手册Synqor中文资料规格书

描述 Description

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).

特性 Features

操作特性
• 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
机械特征
• 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
控制功能
• 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
安全特性
• 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)
保护功能
• 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
