TPS62480是一款適用于薄型負載點電源的同步雙相降壓DC-DC轉換器。此器件的輸入電壓范圍為2.4V至可輸出電流最高可達6A(由兩相持續提供,每相3A),從而允許使用薄型外部組件。兩條電源軌異相運行,可顯著降低脈沖電流噪聲。
TPS62480可在超輕負載時自動進入節能模式以保持高效率。其中包含自動增加/減少相位功能,具體使用一個相位還是兩個相位視實際負載情況而定。
該器件具有電源正常信號和可調節的軟啟動功能。此外,該器件還具有熱性能正常信號,用以檢測內部溫度是否過高。通過VSEL引腳可輸出電壓更改為預選值.TPS62480能夠在100%占空比模式下工作。
TPS62480采用小型3mm×2.5mm HotRod封裝(RNC)。
