數(shù)據(jù): 具有自適應內(nèi)部補償功能的 TPS543B20 4VIN 至 19VIN、25A 可堆疊同步降壓 SWIFT? 轉換器 數(shù)據(jù)表 (Rev. B)
TPS543B20采用內(nèi)部補償?shù)姆抡娣逯惦娏髂J娇刂品绞?,具有適用于EMI敏感型POL的時鐘同步固定頻率調(diào)制器。內(nèi)部積分器和直接放大式斜坡跟蹤環(huán)路在較寬頻率范圍內(nèi)消除了對外部補償?shù)男枨?,從而使用系統(tǒng)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(tài)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25A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TPS543B20器件可以堆疊在一起,以便提供高達50A的負載點。
