CXSU63211是一种高效率的电流模式升压变换器，具有固定的工作频率。CXSU63211在NMOSFET上集成了一个非常低的Rds，以减少功耗并获得更高的效率。最大效率可达93%。当车辆识别号高于3.3V，输出为5V时，CXSU63211CA输出2A电流。高1.2MHz的工作频率使L和C值最小化。内部补偿网络减少了外部元件的数量。小脚印SOT2 3-6封装为PCB版图区域提供了最佳解决方案。

产品概述 返回TOP
The CXSU63211 is a high efficiency current-mode boost converter with a fixed operation frequency. The CXSU63211 integrates a very low Rds-on NMOSFET to reduce power loss and achieve higher efficiency. The maximum efficiency is up to 93%. CXSU63211can output 2A current when Vin is higher than 3.3V and output is 5V. The high 1.2MHz operation frequency minimizes L and C value. The internal compensation network reduces external component counts. Small foot print SOT23-6 package provides the best solution for PCB layout area. CXSU63211is designed with 12V process. This allows CXSU63211to be used in applications where higher voltage is needed, such as charging two Lithium batteries in series. The other possible application where the higher voltage is needed is Qualcomm Quick Charge 2.0 compatible portable chargers. CXSU63211can support 9V Vout for this application.
