The KF6389 is a high efficiency current-mode boost converter with a fixed operation frequency. The KF6389 integrates a very low Rds-on NMOSFTET to reduce power loss and achieve high efficiency. The maximum efficiency is up to 93%. KF6389 can output 2A current when VIN is higher than 3. 3V and output is 5V. 1.2MHz operation frequency minimizes L and C value, and internal compensation network reduces external component counts. SOT23-6 package provides the best solution for PCB layout area.
