數(shù)據(jù): TPS544x25 4.5V 至 18V、20A 和 30A SWIFT 同步降壓控制器(具有 PMBus和頻率同步功能) 數(shù)據(jù)表
TPS544x25器件是采用5mm×7mm封裝且符合PMBus 1.2規(guī)范的非隔離式直流/直流轉(zhuǎn)換器,具有集成的FET,能夠在高頻下運行并輸出20A或30A的電流。集成式NexFET?功率級和經(jīng)優(yōu)化的驅(qū)動器提供的高頻,低損耗開關(guān)支持密度極高的電源解決方案.PMBus接口通過VOUT_COMMAND支持AVS功能,同時支持靈活的轉(zhuǎn)換器配置以及關(guān)鍵參數(shù)(包括輸出電壓,電流和可選的外部溫度)監(jiān)控功能。對故障狀況的響應(yīng)可設(shè)置為重新啟動,鎖存或忽略,具體取決于系統(tǒng)要求。
