The MST9225B is a high efficiency current-mode boostconverter with a fixed operation frequency.
(MST9225B是一種具有固定工作頻率的高效率電流型升壓變換器)
The MST9225B hasbeen integrated a very low Rds-on NMO SFET to reduce powerloss and achieve high efficiency.
(MST9225B集成了一個(gè)非常低的Rds-on NMO場(chǎng)效應(yīng)管,以減少功耗和實(shí)現(xiàn)高效率。)
The maximum efficiency is upto 93%.
(最大效率可達(dá)93%。)
The output Voltage can be programmed by feedbackresistances, and the maximum output voltage is 10V.
(輸出電壓可通過反饋電阻編程,最大輸出電壓為10V。)
MST9225B can output 2A current when VIN is higher than 3.3Vand output is 5V.(當(dāng)VIN大于3.3 v,輸出為5V時(shí),MST9225B可以輸出2A電流。)
1.2MHz operation frequency minimizes L and C value, and internal compensation network reduces external component counts.
(1.2MHz的工作頻率使L值和C值最小化,內(nèi)部補(bǔ)償網(wǎng)絡(luò)減少外部組件計(jì)數(shù)。)
