3A, 1MHz 同步降压型 DC/DC 转换器

RT8089A为高效率的同步降压型DC/DC转换器，输入电压范围为2.7V至5.5V，可调输出电压为0.6V至V_IN ，输出电流可达3A。由于内建同步低导通阻开关可增加效率并不需外加萧特基二极管。内部切换频率恒定于1MHz。100%的工作周期提供了低压降操作，并且延长电池的寿命。由于具有内部补偿机制的电流模式恒定导通时间(CMCOT)操作，可允许系统在大范围的负载变动、输出电容变化的操作条件下仍有优良的瞬时响应特性。RT8089A支持WDFN-10L 3x3封装。 · 效率高达95%\n· 轻载时高效率\n· 低RDS(ON)开关： 69mΩ/49mΩ \n· 恒定频率：1MHz\n· 不需外加萧特基二极管\n· 低压降操作：100%工作周期\n· 过电流保护\n· 欠电压保护 \n· 过热关机保护\n· 符合RoHS规范与无卤特性;
