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.
