Supply input — Nominal operating range is 6V to 42V . 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 V
from 25k to 124k ohms.
Enable — Input to the precision enable comparator. Rising threshold is 1.18V nominal; 90 mV hysteresis nominal.
Maximum recommended input level is 6.5V.
Ground — Reference point for all stated voltages. Must be externally connected to EP.
Soft-Start — An internal 8 µA current source charges an external capacitor to produce the soft-start function. This node
is discharged at 200 µA during disable, over-current, thermal shutdown and internal UVLO conditions.
