NOTE:
(*1) _{When the difference between the input and the output is small, 100% duty might come up and internal control circuits keep P-ch driver turning}
on even though the output current is not so large.
If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance.
(*2) _{Including UVLO detect voltage, hysteresis operating voltage range for UVLO release voltage.}
(*3) _{RLXH=(VIN - Lx pin measurement voltage) / 100mA, RLXL=Lx pin measurement voltage / 100mA}
(*4) _{Design value for the XCL214 series}
(*5) _{Current limit denotes the level of detection at peak of coil current.}
