24V、600mA內(nèi)置開關(guān)、100%占空比、降壓型轉(zhuǎn)換器; ? 固定5V或可調(diào)輸出\n\n? 輸入電壓范圍：4.5V至24V\n\n? 高達600mA輸出電流\n\n? 內(nèi)部0.4Ω P溝道MOSFET\n\n? 效率超過95%\n\n? 靜態(tài)電源電流：15μA\n\n? 關(guān)斷電流：3μA\n\n? 100%最大占空比，以實現(xiàn)低壓差\n\n? 限流架構(gòu)\n\n? 熱關(guān)斷\n\n? 小型8引腳μMAX封裝;

MAX1776高效降壓型轉(zhuǎn)換器可從高達24V的電源電壓提供1.25V至VIN的可調(diào)輸出電壓。內(nèi)部限流0.4Ω MOSFET提供高達600mA的負(fù)載電流。以100%占空比運行可有效減少壓差電壓（600mA時為240mV）。\n\n MAX1776的靜態(tài)電流低至15μA，可提高輕載效率并延長電池使用時間。該器件在關(guān)斷模式下的電流消耗僅為3μA。\n\n 高開關(guān)頻率（高達200kHz）支持使用小型表貼電感和輸出電容。MAX1776采用8引腳μMAX封裝，占用的空間僅為8引腳SO封裝的一半。如需提高輸出驅(qū)動能力，請使用MAX1626/MAX1627降壓型控制器，它們可驅(qū)動外部P溝道MOSFET以提供高達20W的功率。\n\n ?\n\n
