When the IC is in the operation, control is switched to the PWM mode when the CE/MODE pin voltage is equal to or greater than VIN minus 0.3 V, and to the automatic PWM/PFM switching mode when the CE/MODE pin voltage is equal to or lower than VIN minus 1.0 V and equal to or greater than VCEH. *5: Time until it short-circuits VOUT with GND through 1 Ωof resistance from a state of operation and is set to VOUT=0V from current limit pulse generating.
