Note 1: The switching frequency is reduced when the second stage current limit is activated.
Note 2: No diode, inductor or capacitor connected to output pin.
Note 3: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.
Note 4: Feedback pin removed from output and connected to 12V for the 3.3V, 5V, ADJ. version, and 15V for the
12V version, to force the output transistor switch OFF.
