ELECTRICAL CHARACTERISTICS (Continued)
*5: When temperature is high, a current of approximately 10 A (maximum) may leak.
*1: Including hysteresis operating voltage range.
*2: EFFI = { ( output voltage output current )
*3: ON resistance ( )= (V
*4: Design value
*6: The CE/MODE pin of the XCL207 series works also as an external switching pin of PWM control and PWM/PFM control. When the IC is in the
*7: Time until it short-circuits V
*8: When V
*9: When the difference between the input and the output is small, some cycles may be skipped completely before current maximizes.
*10: Current limit denotes the level of detection at peak of coil current.

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
Current Limit
If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance.
