资料介绍

The MST9220B is a high efficiency current-mode boostconverter with a fixed operation frequency. 

(MST9220B是一种工作频率固定的高效率电流型升压变换器)

The MST9220B hasbeen integrated a very low Rds-on NMOS FET to reduce powerloss and achieve high efficiency. 

The maximum efficiency is upto 93%. The output Voltage can be programmed by feedbackresistances, and the maximum output voltage is 10V. 

MST9220B  can output 2A current when VIN is higher than 3.3V and output is5V. 

1.2MHz operation frequency minimizes L and C value, andinternal compensation network reduces external componentcounts. 

SOT23-6 package 

特点:

·Wide Input Range: 2.5-6V Input,(输入范围:2.5-6V输入,

·MST9220B Up To 2A Output Current(MST9220B最大输出电流2A
