數(shù)據(jù): TPS53647 4 相 D-CAP+ 降壓控制器,具有 NVM 和 PMBus? 接口,適用于 ASIC 電源和高電流負載點 數(shù)據(jù)表 (Rev. B)
TPS53647是一款高電流多相位降壓控制器。該器件提供內(nèi)置非易失性存儲器(NVM)和PMBus接口。此款產(chǎn)品與NexFET功率級(CSD95372BQ5MC)兼容.TPS53647提供8位啟動電壓選擇,輸出電壓范圍為0.5V到2.5V,步長低至5mV,非常適合具備精確輸出電壓設置的高電流應用。具有D-CAP +架構(gòu)等高級特性,支持下沖衰減(USR)和過沖衰減(OSR),可實現(xiàn)快速瞬態(tài)響應,最小的輸出電容和高效率.TPS53647還提供新型相位交錯策略和動態(tài)相位減少功能,可有效提升輕量載條件下的效率。此外,TPS53647支持PMBus通信接口,適用于電壓,電流,功率,溫度和故障條件遙測系統(tǒng)。部分配置可通過引腳設置或PMBus編程設定并存儲在非易失性存儲器中,這樣可以減少外部組件的數(shù)量。
TPS53647采用節(jié)省空間,耐熱增強型40引腳QFN封裝,額定運行溫度介于-40°C至125°C之間。
