The Richtek Load Transient Tool makes DC/DC converter stability check simpler and faster than before! No matter your design is a Buck or Boost converter, a linear regulator or even a LED driver, this unique fast load transient tool kit will help you identify loop stability problems and estimate the converter loop control speed to judge the correct control loop compensation. In this tutorial video, you will find an example of a stability test where we compare the load transient test result with an actual open loop gain-phase measurement using a network analyzer. You will also find an example of a stability problem to see the influence of reduced output capacitor value on the converter stability and control bandwidth.

如何使用簡單工具對電源轉換器的穩定性進行測試評估?
大家通常使用網路分析儀對電源轉換器的穩定性進行測量和評估,這種方法得到的數據很準確,但成本也很高昂。由於電源轉換器對脈衝負載的響應特性中,已經包含了穩定性的信息,所以我們可以使用立錡負載瞬變測試工具(Load Transient Tool)來生成快速變化的負載脈衝,再從電源轉換器本身的響應波形中,分析得到電源轉換器本身的環路帶寬、相位裕量等信息,進而以非常低的成本,快速完成穩定性的評估過程。這種方法不僅對 Buck、Boost 轉換器等有用,對 LDO 線性穩壓器、LED 驅動器等也同樣有效。影片中將介紹立錡負載瞬變測試工具,以及它在實際中的應用方法,讓您快速了解相關技術和實現方法。
