Notes : 5. These parameters are not tested on each unit. They are measured during our internal qualification.
6. Duty Cycle is the ratio between the output transistor OFF time and the period. The power transistor is controlled OFF when the
output transistor is OFF.
7. Initial Condition for Safe Operation Start Up
8. See Figure 14.
9. S and C correction are inhibited so the output sawtooth has a linear shape.
