400mA同步整流DC/DC轉換器
XC9245系列產品是能使用陶瓷電容,內置0.65ΩP溝道驅動晶體管及0.45ΩN溝道開關晶體管的降壓同步整流DC/DC轉換器。只使用線圈和電容作為外置零部件,能穩定地提供最大400mA的電流。
XC9245系列產品內部設定了輸出電壓,能在0.8V~4.0V的範圍內(±2.0%)以0.05V的間隔選擇輸出電壓。開關頻率高達1.2MHz,能減小外置零部件的尺寸。採用USPN-6封裝。 USPN-6封裝最適用於對高度及空間有限制的應用。
由於在待機時整個電路停止工作,能把消耗電流抑制在1.0μA以下。在待機時,由CL高速放電功能使VOUT-VSS之間的內部開關導通,通過內部電阻使CL的電荷放電。這個功能可以在待機時防止VOUT後續電路的錯誤動作。
由內部把軟啟動時間設定為0.25ms(TYP.),能使輸出電壓高速地上升。
為了保護IC不受熱損壞,XC9245系列產品備有積分鎖定方式的限定電流功能。內置了UVLO (輸入欠壓鎖閉Under Voltage Lock Out) 功能,在輸入電壓低於2.25V(最大)時,強制停止內部驅動晶體管工作。
