描述 Description

The PQ60050EGL15 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.

特性 Features

操作特性
? High efficiency, >89% at full rated load current
? Delivers up to 15 amps of output current (75W) 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
