2A, 2.25MHz 同步降壓DC/DC轉(zhuǎn)換器

EUP3260A是一款應(yīng)用于電池供電的便攜式設(shè)備的同步降壓DC/DC。2.7V到5.5V的輸入電壓范圍使EUP3260A適合工作在一節(jié)鋰電池或三節(jié)的鎳氫電池/鎳鉻電池的便攜式設(shè)備。該芯片也可工作于標(biāo)準(zhǔn)的3.3V或5V電壓。\nEUP3260A工作在2.25MHz的固定開關(guān)頻率下，允許應(yīng)用小的電感和電容以節(jié)省面積。內(nèi)部同步開關(guān)管提升效率并無需外部肖特基二極管。EUP3260內(nèi)部集成了軟啟動(dòng)功能，避免了電流啟動(dòng)過程中電流的過充。\nEUP3260A具有可供選擇的force PWM和PFM/PWM模式。force PWM模式的紋波噪聲小，而PFM模式具有輕載高效的優(yōu)勢。EUP3260A采用TDFN- ?高至95%的效率\n?2.25MHz的固定頻率\n?2A負(fù)載電流能力\n?典型30μA的靜態(tài)電流\n?2.7V到5.5V的輸入電壓范圍\n?低至0.6V的可調(diào)輸出電壓\n?無需肖特基二極管\n?短路保護(hù)和過溫保護(hù)\n?內(nèi)部軟啟動(dòng)功能\n?TDFN-6/SOT23-5的封裝\n?符合RoHS標(biāo)準(zhǔn)和100%無鉛;
