*1 : Designed value
*2 : Efficiency ={(output voltage) X (output current)} ÷ {(input voltage) X (input current)} X 100
*3 : LX SW "P-ch" ON resistance=（VLx-VOUT pin test voltage）÷100mA
*4 : Testing method of LX SW "N-ch" ON resistance is stated at test circuits.
*5 : Current flowing through the Nch driver transistor is limited.
*6 : The XC9128D/XC9129D series does not have integral latch protection and VLVP function.
This is only available with the XC9128B/XC9129B series.
*7 : The XC9129 series does not have FO and AEN/ pins. These pins are only available in the XC9128 series.
*8 : The XC9129 series does not have FO and AEN/ pins. The AEN/FO functions are only effective for the test of the XC9128 series.
