3.OVP(Over Voltage Protection)
The stopping operation is kept until the voltage of VIN is lower than 7.3V. If the voltage of VIN pin is higher than 9V, the
switching operation is restated.
4. TSD(thermal Shut Down protection
stops. The IC starts switching operation again when the junction temperature is 135°Ctyp (B) or lower.
Skip frequency function
If the voltage of VIN pin is higher than the internal reference voltage VINOVP(27Vtyp),switching operation is stopped.
The thermal shutdown function works when the junction temperature of IC is 165deg (typ) (A), and the IC switching
outputstage
LV5026M contains the skip frequency function for reduction of the peak value of conduction noise. This function
