Notes: 1.The switching frequency is reduced when the second stage current limit is activated.

2.No diode, inductor or capacitor connected to output pin.

3.Feedback pin removed from output and connected to 0V to force the output transistor switch ON.

4.Feedback pin removed from output and connected to 15V for the 12V version, and 12V for others to force

the output transistor switch OFF.
