Note 1: External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system

performance. Refer to Application Information for details.

Note 2: 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%.
