PQ40120QGx08数据手册Synqor中文资料规格书

描述 Description

The PQ40120QGx08 PowerQor® Giga quarter‑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 for greater reliability. The PQ40 module offers a wide input voltage range to cover both 24V and 48V applications. RoHS compliant (see the last page).

特性 Features

操作特性
• High efficiency, 90% at full rated load current
• Delivers up to 8.33A of output current (100W) with minimal derating
- no heatsink required
• Ultra wide input voltage range: 18V – 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 pin-out configuration
• Standard Size: 2.30\"x1.45\"x0.397\" (58.4x36.8x10.08mm)
• Weight: 1.2 oz. (34 grams)
• Flanged pins designed to permit surface mount soldering, avoid wave solder using FPiP technique on open frame units
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
• CAN/CSA C22.2 No. 60950-1
• UL 60950-1
• EN 60950-
保护功能
• Input under-voltage lockout disables converter at low input voltage
• Output current limit and short circuit protection protects converter from excessive load current or short circuits
• 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 protectsconverer from abnormal environmental conditions
