交叉工作、高效、雙電源控制器，用于筆記本電腦

MAX8716/MAX8717/MAX8756/MAX8757是雙路、降壓型、交錯(cuò)工作、固定頻率、開關(guān)電源(SMPS)控制器，具有同步整流功能。MAX8716/MAX8717/MAX8756/MAX8757是專門用于產(chǎn)生主電源(5V/3.3V)，而MAX8756經(jīng)過優(yōu)化用于為電池供電系統(tǒng)的I/O供電。\n 在從最低到最高26V的電壓輸入范圍內(nèi)，交錯(cuò)優(yōu)化的固定開關(guān)頻率可將輸入波紋降至最低。在5V/3.3V應(yīng)用中，優(yōu)化的40/60交錯(cuò)工作允許輸入電壓降低至8.3V而不會出現(xiàn)占空比交疊，而180°異相工作的調(diào)節(jié)器在輸入電壓降至10V以下是即出現(xiàn)占空比重疊。\n 可采用檢流電阻實(shí)現(xiàn)精確的輸出電流限制。 \n? 固定開關(guān)頻率\n? 200kHz、300kHz或500kHz \n? 250kHz、300kHz或400kHz (僅MAX8756) \n? 無需檢流電阻 \n? 40/60優(yōu)化交錯(cuò) \n? 輸入電容要求較低 \n? 固定輸出或可調(diào)輸出(Dual Mode?) \n? 3.3V/5V固定或1V至5.5V可調(diào)輸出 \n? 1.5V/1.8V固定或1V至2.3V可調(diào)輸出(僅MAX8756) \n? 4V至26V輸入范圍 \n? 獨(dú)立選擇PWM、跳脈沖和低噪聲工作模式 \n? 軟啟動和軟關(guān)斷 \n? 0.75%精度的2V基準(zhǔn) \n? 獨(dú)立電源良好輸出;
