3. The oscillator frequency reduces to approximately 18 kHz in the event of an output short or an overload which causes the regulated output  
voltage to drop approximately 40% from the nominal output voltage. This self protection feature lowers the average dissipation of the IC by  
lowering the minimum duty cycle from 5% down to approximately 2%.  
4. Output (Pin 2) sourcing current. No diode, inductor or capacitor connected to output pin.  
5. Feedback (Pin 4) removed from output and connected to 0 V.  
6. Feedback (Pin 4) removed from output and connected to +12 V for the Adjustable, 3.3 V, and 5.0 V versions, and +25 V for the 12 V and  
15 V versions, to force the output transistor “off”.  
7. V = 40 V.
