DCDC变换器布局布线参考文档，以LM5175为例(Fundamental to careful system design of any DC/DC power converter is a well-planned and carefully executed printed circuit board (PCB) layout. An optimized layout leads to better performance, lower cost and faster time-to-market. Additionally, it can constitute a competitive advantage for the end equipment user owing to higher reliability (lower component temperature), easier regulatory compliance (lower conducted and radiated emissions), and improved space utilization (reduced solution volume and footprint))
