PQ24018QGx25中文资料DC-DC Converter数据手册Synqor规格书

描述 Description

The PQ24018QGx25 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. Since the PowerQor converter has no explicit thermal connections, it is extremely reliable. RoHS Compliant, see last page.

特性 Features
