MIC2193/MI***690系列替换方案。XC9220/XC9221系列是多用途,***DC/DC控制器IC可替代MIC2193/MI***690芯片。XC9220/XC9221系列适应环保要求：与EUROHS规格对应、无铅。工作电压范围：2.8V~16V（******大额定值：18.0V），输出电压外部设定：0.9V（精度：&plu***n;1.5%），控制方式：WM/PFM自动切换，软启动功能：4ms，工作温度：-40°C--+85°C。XC9221系列是PWM/PFM控制,当负载变轻它能从PWM自动切换到PFM,因而在整个负载范围都能保持***率。关于软启动时间,XC9221是内部设定为4毫秒.具有内置的U.V.L.O.(欠压锁闭)功能,当输入电压低至2.3V或更低的时候,外部的P沟道开关管会被强制关断。有两种封装SOT-25和USP-6可供选择。更多替代型号：TOREX品牌替代的品牌可替代的型号XC9128MaximSemiconductorMAX1947XC9235MaximSemiconductorMAX1733XC9221x035xRMicrelSemiconductorMIC2193XC9221A09AMRMicrelSemiconductorMI***690XC9223B082ARMicrelSemiconductorMIC3838XC9220MicrelSemiconductorMIC2193XC9224MicrelSemiconductorMIC3838XC6368CxxxMRMicrochipTC110XC9201MicrochipTC105XC6372MicrochipTC115XC6366CxxxMRMicrochipTC105XC9235NationalSemiconductorLM3674XCM517NationalSemiconductorLM2717XC9208NationalSemiconductorLM3677XC9210NationalSemiconductorLM2650XC6371NationalSemiconductorLM2703XC9119D10AMRNationalSemiconductorLM2703XC6365A303ERNationalSemiconductorLM3677XC9206A18MRNationalSemiconductorLM3677XC9207A18MRNationalSemiconductorLM3677XC9213B103VRNationalSemiconductorLM2594XC9213B103VRNationalSemiconductorLM2676XC9213B103VRNationalSemiconductorLM2737XC9301NationalSemiconductorLM2716XC9302NationalSemiconductorLM2716XC9235OnSemiconductorsNCP1522XC9236OnSemiconductorsNCP1522XC9237OnSemiconductorsNCP1522XC9103OnSemiconductorsNCP1406XC9105OnSemiconductorsNCP1406XC9106OnSemiconductorsNCP1403XC9107OnSemiconductorsNCP1403XC9201OnSemiconductorsNCP1550XC9210OnSemiconductorsNCP1508XC9111OnSemiconductorsNCP1400XC9104B095xROnSemiconductorsNCP1406XC911950AMROnSemiconductorsNCP1402)
