Note 2:
External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance.
Refer to Application Information for details.
The oscillator frequency reduces to approximately 11kHz in the event of fault conditions, such as output short or overload. And the
regulated output voltage will drop approximately 40% from the nominal output voltage. This self-protection feature lowers the average
power dissipation by lowering the minimum duty cycle from 5% down to approximately 2%.
For these parameters, FB is removed from VOUT and connected to +12V to force the output transistor OFF.
VOUT pin sourcing current. No diode, inductor or capacitor connect to VOUT.
FB is removed from VOUT and connected to 0V.
