Run mode is the normal operating mode of the controller when not in UVLO mode or standby mode. In this mode, REG current is higher because all internal control and timing functions are operating and the VG output is driving the MOSFET for synchronous rectification. REG current is the sum of IVDDRUN plus the average current necessary to drive the load on the VG output. The VG voltage is automatically adjusted based on the SR MOSFET drain to source voltage according to the proportional gate drive operation.
