operation, control is switched to the automatic PWM/PFM switching mode when the CE/MODE pin voltage is equal to or greater than V
0.3V, and to the PWM mode when the CE/MODE pin voltage is equal to or lower than V
If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance.
