7.2.2.1.2 Switching Frequency and MODE Selection

Switching Frequency, current limit, and switching mode (DCM or FCCM) are set by a voltage divider from VREG5 to GND connected to the MODE pin. See Table 6-3 for possible MODE pin configurations. Switching frequency selection is a tradeoff between higher efficiency and smaller system solution size. Lower switching frequency yields higher overall efficiency but relatively bigger external components. Higher switching frequencies cause additional switching losses which impact efficiency and thermal performance. For this design, 1.2 MHz is chosen as the switching frequency, the switching mode is DCM and the output current is 12 A.
