【应用】AIT降压IC A7231AE6VR用于网关项目中,输出电流3A,转换效率高达96%
在网关项目当中需要对12V电压降压至3.3V给各个模块供电,这里选择了AIT的A7231AE6VR,该降压IC的输入电压是4.2V~16V,输出电流可达3A,转换效率高达96%,可以满足在这个项目当中给各个模块供电的需求。以下是该项目的大致框图:
以下是该IC的参数表:
从该表可知输入电压是4.2V~16V,待机功耗低在5μA,开关上限电流为6A,最大占空比为92,优异的性能参数可以满足其它很多项目的设计需求。
以上是该IC的典型运用电路和输出电压调节公式调节R1和R2阻值比例输出想要的工作电压,用法简单方便。从上可以看出该DCDC降压的性能可以很好的运用于该项目当中,而且AIT做为一个资深品牌,在研发设计中可以放心选用。

AIT Buck Converter技术讲解 ∣视频
AiT介绍了A7142的经典电路图、DCDC转换的基本电路;介绍DCM和CCM之间的区别以及各自的优缺点。
【选型】国产DCDC SCT2450可P2P替换TI TPS54540,静态电流低至25μA
某客户研发一个工业IOT无线网关模块的项目,用到TI的电源芯片TPS54540DDA,因TI的交期比较久,本文推荐用芯洲科技的DCDC降压芯片SCT2450替换TPS54540。
广泛用于笔电、无线调制解调器、平面电视的高效率电流模式buck IC AiT SEMi A7222,2A/500KHz
创瑞科技A7222是一款电流模式高效率2A同步整流降压DC/DC转换器,无需额外的外部补偿组件即可提供出色的瞬态响应,支持PWM控制和PFM模式开关。
A7406 DC-DC转换器降压(降压型)
描述- A7406是一款同步降压型DC-DC转换器IC,具有低导通电阻的两只NMOSFET功率开关。输入电压范围为4.7V至40V,可提供高达1A的负载电流。在轻载条件下,A7406工作在PFM模式,具有良好的效率;重载时切换频率恒定为1MHz。该产品具备过温保护、短路保护和循环周期峰值电流限制等功能。
型号- A7406E6R,A7406E6VR,A7406
【选型】A7596 DCDC降压芯片pin to pin替换TI的LM2596用于手持吸尘器
在手持吸尘器产品中,一般采用TI的DCDC降压芯片LM2596将输入供电的6节串锂离子电池电压值降压至5V后供后级电路使用,该处的电耐压需求36V以上,电流值根据5V电机的需求选择,由于近期中美贸易战影响,部分厂商开始寻找该物料的替换料,本文给大家介绍一款创瑞(AIT)科技的DCDC产品A317B,可以pin to pin替换LM317,无需更改电路中的其他器件,保证简单高效的实现物料替换。
