以 DC/DC 切換穩壓器實現低雜訊與低 EMI 性能
工程師認為降低切換穩壓器 EMI 與雜訊深具挑戰性。若過度擺弄 PCB 佈局的配置，系統就可能無法通過 CISPR 標準。因此，許多電源設計人員直接轉為使用線性穩壓器，藉此確保可避開需減少發射量的頭痛問題。但線性穩壓器的效率不彰，因此會帶來潛在的熱問題，而使用切換穩壓器則可避免發生此問題。該如何才能兩全其美？本訓練系列與文件旨在說明工程師可如何讓切換器發揮卓越效率，同時還可克服 EMI 與雜訊的挑戰。在內容中會介紹 EMI 與雜訊最佳實務的概念與實際範例，以及關於對汽車系統及對雜訊敏感之類比電路供電的具體意見。若能熟悉各種用於調節傳導式和輻射式 EMI 的標準，可能會有所幫助。
