0.5V低輸入電壓 1A 高速電壓穩壓器(附帶外部調整軟啟動時間的功能)
XC6603系列產品能從0.5V的輸入電壓開始工作。此外,因為是超低導通電阻,最適用於需要在低電壓同時高效率地輸出大電流的應用。輸出電壓為±15mV/±20mV且精度高,內部由N溝道驅動晶體管,基準電壓源,誤差放大器,過電流保護電路(反饋),過熱保護電路(TSD),欠壓鎖閉電路(輸入欠壓鎖閉),軟啟動電路,相位補償電路等構成。
輸出電壓由內部激光微調固定,能在0.5V~1.8V的範圍內以0.1V的間隔選擇產品。輸出濾波電容(CL)還能對應陶瓷等低ESR電容。
在IC啟動時,軟啟動電路給CL充電,能抑制從VIN急劇地流向VOUT的衝擊電流,能抑制從VIN急劇地流向VOUT的衝擊電流。通過調節SS引腳連接的電容能任意地設定軟啟動時間。因為衝擊電流與軟啟動時間成相反的關係,設定延長軟啟動時間能抑制衝擊電流。
通過CE引腳使IC成待機狀態能大幅度降低消耗電流。此外,由內部開關能使CL中的充電電荷高速放電,迅速地返回VSS電平。並且,在IC內部CE引腳內置下拉電阻,在CE未連接電平時,使IC成待機狀態。
