4.1.1 MODE Pin

The threshold voltages for FPWM and PSM modes are 1.19V and 0.41V, respectively. When the voltage at the MODE pin rises above 1.19V, the converter switches to FPWM mode, allowing backward operation and causing the storage element to charge. Conversely, when the voltage falls below 0.41V, the converter operates in forward mode only and stops the charging.
