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 when the second stage current limit is activated. The amount of reduction is
determined by the severity of current over load.
Note 3: For these parameters, FB is removed from V
OUT
and connected to +12V to force the output transistor OFF.
