10) Safety functions
10-1) Over voltage detect function (OVP)
When OVP become more than 5.5V, IC stop the switching.
When OVP become less than detect voltage, the status of switching will restart.
10-2) Open detect function (ODF)
When OVP pin is not connected any components, IC will stop the switching.
