A small amount of internal capacitance is contained within the package assembly. Additional external input capacitance is required between this pin and exposed pad. On Time Resistor - An external resistor from VIN to this pin sets the on-time of the application. Typical values range from 25k to 124k ohms. Enable - Input to the precision enable parator. Rising threshold is 1.18V nominal; 90 m V hysteresis nominal. Maximum remended input level is 6.5V. Ground - Reference point for all stated voltages. Must be...
