描述 Description

The PQ60033EGx20 PowerQor? Giga 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 12).

特性 Features

操作特性
? High efficiency, 89% at half load, >87% at full load
? Delivers up to 20 amps of output current (66W) 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
機(jī)械特征
? Industry standard eighth-brick pin-out configuration
? Industry standard size: 0.90\" x 2.3\" (22.9x58.4 mm)
? Total height of the EGL is only 0.340\" (8.64 mm), permitting better airflow and smaller card pitch
? Total weight: 0.68 oz (19 g)
? 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
? 2000V, 30 MW input-to-output isolation provides input/output ground separation
? UL 60950-1 recognized (US & Canada), basic insulation rating
? TUV certified to EN60950-1
? 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 flammability requirements
保護(hù)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
