高效率的电流模式升压具有固定工作频率的变频器MST9225B
The MST9225B is a high efficiency current-mode boostconverter with a fixed operation frequency.
(MST9225B是一种具有固定工作频率的高效率电流型升压变换器)
The MST9225B hasbeen integrated a very low Rds-on NMO SFET to reduce powerloss and achieve high efficiency.
(MST9225B集成了一个非常低的Rds-on NMO场效应管,以减少功耗和实现高效率。)
The maximum efficiency is upto 93%.
(最大效率可达93%。)
The output Voltage can be programmed by feedbackresistances, and the maximum output voltage is 10V.
(输出电压可通过反馈电阻编程,最大输出电压为10V。)
MST9225B can output 2A current when VIN is higher than 3.3Vand output is 5V.(当VIN大于3.3 v,输出为5V时,MST9225B可以输出2A电流。)
1.2MHz operation frequency minimizes L and C value, and internal compensation network reduces external component counts.
(1.2MHz的工作频率使L值和C值最小化,内部补偿网络减少外部组件计数。)
ESOP-8 package provides the best solutionfor PCB heat dissipation.(ESOP-8封装为PCB散热提供了最佳解决方案。)
