■FUNCTION CHART

Note on CE/MODE pin voltage level range

(*1) H level: 0.65V < H level < VIN V (for XC9235/XC9236)

H level: VIN – 0.25V < H level < VIN (for XC9237)

(*2) M level: 0.65V < M level < VIN - 1.0V (for XC9237)

(*3) L level: 0V < L level < 0.25V

＜Soft Start＞

Soft start time is available in two options via product selection.

The XC9235A/XC9236A/XC9237A/XC9235C/XC9236C/XC9237C series provide 1.0ms (TYP). The XC9225B/XC9236B/XC9237B series

provide 0.25ms (TYP). Soft start time is defined as the time to reach 90% of the output setting voltage when the CE pin is turned on.
