NOTE:

High Speed (HS) mode: The voltage of VGOH or more is input to the GO pin, or the voltage of VGOL or less is input to the GO pin

when the output current is IGO or more.

Power Save (PS) mode: The voltage of VGOL or less is input to the GO pin when the output current is IGOR or less.

* 7: With the GO pin input voltage, the fixed HS mode or Green Operation (GO) is selectable.

* 8: For the XC6207B series only. The XC6207A series discharges by resistors R1 and R2 only as shown in the block diagrams.
