9.2.2.3 MODE Selection

The light load running mode (Eco-mode or FCCM ) are set by a voltage divider from VCC to GND connected to the MODE pin. See Table 1 for possible MODE pin configurations. For this design example ,the switching frequency is about 500kHz, the light load running mode is Eco-mode and the output current is 12 A.
