PQ60025EKx20中文资料DC-DC Converter数据手册Synqor规格书

描述 Description

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).

特性 Features

操作特性
• 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
机械特征
• 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
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
• 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
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
