RT8048為高效率,脈波寬度調變(PWM)的降壓型 DC/DC 轉換器,可輸入範圍2.5V 至5.5V,輸出電流可達1A,適用于由單一鋰電池供電的可攜式電子裝置,例如行動電話、PDA等掌上型裝置。RT8048具有兩種操作模式:可自動切換PWM/低壓差 操作狀態的工作模式與關機模式。由於內建低R<sub>DS(ON)</sub的同步整流元件,可大幅減低操作在PWM模式時的電流導通損耗。此外,不需外加蕭特基二極體於實際設計中。RT8048當PWM操作時無法連續導通上端P-MOSFET時,進入低壓降模式。當EN腳位為低電位時,進入關機模式,消耗電流小於0.1μA。由於操作在固定頻率3MHz,切換漣波可由較小封裝的元件進行濾波設計
