Fig.5
Timing diagram for the frequency regulation mode showing the voltage on external capacitor C5
connected between CX and ground and the output voltage as a function of time for three combinations of
input signals. a: The voltages on inputs FB or LIM are between 2,2 V and 5,9 V. The circuit is in its normal
regulation mode. b: The voltage on input FB or input LIM is lower than 2,2 V. The circuit works at its
maximum frequency. c: The voltages on inputs FB and LIM are higher than 5,9 V. The circuit works at its
minimum frequency.
