■OPERATIONAL DESCRIPTION (Continued)
＜Soft Start＞
■FUNCTION CHART
Soft start time is available in two options via product selection.
The A,C,D,and E types of XC9235/XC9236/XC9237 series provide 1.0ms (TYP).
The B,F, and G types of XC9235/ XC9236/XC9237 series provide 0.25ms (TYP). However, for the D/F the soft-start time can
be set by the external components. Soft start time is defined as the time interval to reach 90% of the output voltage from the
time when the CE pin is turned on.
Note on CE/MODE pin voltage level range
(*1) H level: 0.65V < H level < V
(*2) M level: 0.65V < M level < V
(*3) L level: 0V < L level < 0.25V
