TOFF adjustment
The OFF time is adjusted through an external resistor connected between the TOFF pin and
ground as shown in Figure 7.
Figure 7. OFF time regulation circuit
The relation between the OFF time and the external resistor value is shown in the graph of
Figure 8. The value typically ranges from 10 µs to 150 µs.
The recommended value for ROFF is in the range between 5 k and 180 k.
