【产品】1.5MHz,1.5A恒定频率的单片式同步降压稳压器A7115,效率高达96%
AIT推出的A7115是一款采用恒定频率,电流模式架构的高效单片式同步降压稳压器。该产品在空载时的供电电流为300μA,关断时供电电流降至<1μA,输入电压范围为2.5V~6.5V,非常适用于单节锂离子电池,2节或4节AA电池供电。
A7115单片式同步降压稳压器的占空比为100%,可提供低压差操作,延长便携式系统的电池寿命。该产品的PWM脉冲跳跃模式操作可为噪声敏感应用提供极低的输出纹波电压,开关频率在内部设置为1.5MHz,允许使用小型表面贴装电感和电容。A7115的内部同步开关提高了效率,免除了增设一个外部肖特基二极管的需要。利用0.6V反馈参考电压可轻松支持低输出电压。
