MAX1640 | 可調(diào)輸出、開關(guān)模式電流源,內(nèi)置同步整流 MAX1640/MAX1641 CMOS、可調(diào)輸出、開關(guān)模式電流源采用+5.5V至+26V輸入工作,非常適合用于微處理器控制的電池充電器。充電電流、最大輸出電壓和脈沖涓流充電可通過外部電阻進行編程設(shè)置??梢酝ㄟ^對關(guān)斷時間進行編程來修改開關(guān)頻率,從而抑制噪聲敏感型電路中不必要的諧波。MAX1640的高側(cè)電流檢測技術(shù)支持將負載直接接地,消除了地電位誤差。MAX1641采用低側(cè)電流檢測技術(shù)。\n\n MAX1640/MAX1641降壓型脈寬調(diào)制(PWM)控制器使用外部P溝道MOSFET開關(guān)和可選的外部N溝道MOSFET同步整流器以提高效率。內(nèi)部低壓差線性穩(wěn)壓器為內(nèi)部基準電壓源和電路以及N溝; ? 效率:95%\n\n? 輸入電源范圍:+5.5V至+26V\n\n? 2V至24V可調(diào)輸出電壓范圍\n\n? 100%最大占空比(低壓差)\n\n? PWM工作頻率高達500kHz\n\n? 可選同步整流器\n\n? 16引腳QSOP封裝\n\n? 電流檢測精度:\n? 2% (MAX1641)\n\n? 5.3% (MAX1640); | ADIAnalog Devices 亞德諾亞德諾半導(dǎo)體技術(shù)有限公司 | ||
