【经验】AIT 3A同步整流降压转换器A7231A在应用中所需电感和输出电压纹波的计算方式
AIT创瑞A7231A是一款电流模式、高效率的3A同步整流降压转换器,集成了120mΩ内阻的高边MOS和60mΩ内阻的低边续流MOS。具有宽输入电压范围4.2-16V,可以持续输出3A的工作电流。
该器件提供两种工作模式,PWM模式和PFM模式,工作频率500kHz,可在低负载情况下提供高转换效率,最高效率达96%。此外,它还有OCP打嗝保护模式、OTP、软启动等功能。封装为SOT-26。典型应用电路图如下:
应用设计经验:
1、对于大多数应用,使用2.2μH至10μH的电感,其直流额定电流至少比最大负载电流高25%。为了达到更高的转换效率,建议选用直流电阻DCR小于15mΩ的电感。在轻负载条件下(100mA以下),可选用较大的电感,以提高效率。电感值的计算公式为:
2、输出纹波的计算,对于不同的电容,分两种情况来计算:
A、对于陶瓷电容,在开关频率处,电容容量在阻抗中占主导地位,并导致大部分输出电压的纹波。输出电压纹波的估算公式为:
B、对于钽电容或电解电容,ESR在开关频率处占主导地位。输出纹波可近似为:
3、为了使环路更稳定,可在输出调压处的上下两分压电阻的中点和FB引脚之间串接一个电阻,如右图所示:

传统的电动自行车轻小,但是不便携,两轮电动滑板车可折叠、同时更轻量,广泛引起城市用户特别是年轻用户的喜爱。 如图为36V/350w的电动滑板车驱动电路图框,主要包含36V电池组、主功率MOS管驱动模块、以及电源模块:高压DC-DC初级转换12V/次级DC-DC转换成5V,以及mcu控制模块等组成;这里因为电池组充满电后,供电电压可超过36V,而mcu、通讯IC等均需要低电压5V供电,直接转换成5
【产品】集成式、高效率的同步整流DC/DC降压变换器A7231A
AIT推出的A7231A是一款集成式、高效率的同步整流DC/DC降压变换器,该产品提供两种工作模式,即脉冲调制(PWM)控制和功率因素校正(PFM)模式切换控制,这两种模式可以实现在更宽的负载范围内实现高效率。主要应用于分布式电力系统,数字机顶盒,平板电视和监视器,无线和DSL调制解调器,笔记本电脑等产品。效率高达96%,工作频率500kHz,输出电流3A。
