采用 2mm x 2mm DFN 封裝的 500mA 1MHz 同步升壓型 DC/DC 轉(zhuǎn)換器

LTC3526/LTC3526B是同步固定頻率升壓DC/DC轉(zhuǎn)換器，支持輸出斷開。同步整流使其能在2mm × 2mm小型DFN封裝中實(shí)現(xiàn)高效率。啟動電壓為850mV，在啟動之后工作電壓可以低至500mV，這進(jìn)一步延長了由單節(jié)AA/AAA電池供電的產(chǎn)品的電池續(xù)航時間。\n\n開關(guān)頻率為1MHz，這使其能夠使用微型電感和陶瓷電容，盡可能減小了解決方案的尺寸。電流模式PWM設(shè)計支持內(nèi)部補(bǔ)償，減少了外部組件的數(shù)量。LTC3526支持在輕負(fù)載條件下使用自動突發(fā)工作模式，LTC3526B則能在輕負(fù)載條件下進(jìn)行連續(xù)開關(guān)?？锅Q抑制控制電路還能在非連續(xù)模式下抑制電感，幫助緩解EMI問題。其他特性包括低關(guān)斷電流可 ? 可從單節(jié)堿性 / NiMH 電池提供 3.3V/100mA 輸出，或者從兩節(jié)電池提供 3.3V/200mA 輸出 \n\n? VIN 啟動電壓：850mV \n\n? VOUT 范圍：1.6V 至 5.25V \n\n? 效率高達(dá) 94% \n\n? 輸出斷接 \n\n? 1MHz 固定頻率操作 \n\n? 可在 VIN > VOUT 的條件下操作 \n\n? 集成軟起動功能;
