*1 : The minimum value of AVDD = DVDD1 = DVDD2 is the 2.5 V or VOUT setting value + 0.6 V, whichever is higher.
*2 : The + leak at the LX pin includes the current of the internal circuit.
*3 : Sum of the current flowing into the AVDD, the DVDD1, and the DVDD2 pins.
*4 : Current consumption based on 100% ON-duty (High side FET in full ON state). The SW FET gate drive current is
not included because the device is in full ON state (no switching operation). Also the load current is not included.
