The efficiency of TJ6713 at light load (10m A) is up to 80%, and efficiency at heavy load is up to 94%. The TJ6713 operates at a fixed frequency of 1MHz. The high operating frequency minimizes the size of external ponents. Internal soft-start circuitry reduces inrush current. Short-circuit and thermal-overload protection improve design reliability.
