APW7314
Function Description
Frequency Foldback
The foldback frequency is controlled by the FB voltage.
When the output is shortened to the ground, the frequency
of the oscillator will be reduced to 0.25 x F . This lower
SW
frequency allows the inductor current to safely discharge,
there by preventing current runaway. The oscillator’s fre-
quency will gradually increase to its designed rate when
the feedback voltgae on FB again approaches 0.807V.
