高效率1.2MHz 2A升壓轉換器

SDB628是一款固定頻率，SOT23-6封裝的電流模式升壓變換器，高達1.2MHz的工作頻率使得外圍電感電容可以選擇更小的規(guī)格。內置軟啟動功能減小了啟動沖擊電流。SDB628輕載時自動切換至PFM模式。SDB628包含了輸入欠壓鎖定，電流限制以及過熱保護功能。小尺寸的封裝給PCB省下更多的空間。 ● 1.2MHZ固定開關頻率\r\n\r\n● 內部集成軟啟動\r\n\r\n● 支持低至1.6V輸入電壓范圍\r\n\r\n● 3.3V入5V出,可以輸出800mA\r\n\r\n● 3V入3.3V出,可以輸出800mA\r\n\r\n● 超小型SOT23-6封裝;
