          Low-Voltage, 400mA Step-Down DC-DC Converters in SOT23

          General Description The MAX1920/MAX1921 step-down converters deliver over 400mA to outputs as low as 1.25V. These converters use a unique proprietary current-limited control scheme that achieves over 90 efficiency. These devices maintain extremely low quiescent supply current (50μA), and their hi

          低電壓、400mA、降壓型DC-DC轉(zhuǎn)換器,SOT23封裝

          MAX1920/MAX1921降壓型轉(zhuǎn)換器可輸出最低1.25V的電壓,同時(shí)提供超過400mA的電流。這兩個(gè)轉(zhuǎn)換器使用獨(dú)特的限流控制技術(shù)可獲得高于90%的效率。這兩個(gè)器件具有超低靜態(tài)工作電流(50μA)、高達(dá)1.2MHz (最高)的開關(guān)頻率,允許選用小尺寸、低成本的外部元件。這些特點(diǎn)使MAX1920/MAX1921在空間受限應(yīng)用中成為線性穩(wěn)壓器出色的、高效替代品。\n\n 內(nèi)置同步整流極大地改善了效率,無需使用傳統(tǒng)降壓型轉(zhuǎn)換器中所必需的外部肖特基二極管。兩個(gè)器件還包括內(nèi)部數(shù)字軟啟動,用于限制啟動過程的輸入電流、降低對輸入電容的要求。\n\n MAX1920提供可調(diào)輸出 ? 保證400mA輸出電流\n? 內(nèi)置同步整流,效率>90%\n? 小巧的6引腳SOT23封裝\n? 高達(dá)1.2MHz開關(guān)頻率,小尺寸的外部元件\n? 50μA靜態(tài)工作電流\n? 0.1μA邏輯控制關(guān)斷電流\n? 2V至5.5V輸入電壓范圍\n? 固定1.5V、1.8V、2.5V、3V和3.3V輸出電壓(MAX1921)\n? 可調(diào)輸出電壓(MAX1920)\n? ±1.5%初始精度\n? 軟啟動限制啟動電流;
