數據: 具有自適應內部補償功能的 TPS543C20 4VIN 至 16VIN、40A 可堆疊同步降壓 SWIFT? 轉換器 數據表 (Rev. A)
TPS543C20采用內部補償的仿真峰值電流模式控制方式,具有適用于EMI敏感型POL的時鐘同步固定頻率調制器。內部積分器和直接放大式斜坡跟蹤環路在較寬頻率范圍內消除了對外部補償的需求,從而使用系統設計具有靈活,密集和簡單的特點。可選的API和體制動功能有助于分別通過顯著減少下沖和過沖來提高瞬態性能。具有低損耗開關特性的集成式NexFET?MOSFET有助于提高效率和提供高達40A的輸出電流(采用5mm×7mm的PowerStack?封裝,帶有方便布局的散熱墊) 。兩個TPS543C20器件可以堆疊在一起,以便提供高達80A的負載點。
