Oscillator internal block diagram
The following approximate relationships hold for the minimum and the maximum oscillator
frequency respectively:
Equation 1
After fixing CF in the hundred pF or nF range (consistent with the maximum source
capability of the RFmin pin and trading this off against the total consumption of the device),
the value of RFmin and RFmax is selected so that the oscillator frequency is able to cover the
entire range needed for regulation, from the minimum value fmin (at minimum input voltage
and maximum load) to the maximum value fmax (at maximum input voltage and minimum
load):
Equation 2
A different selection criterion is given for RFmax in case burst-mode operation at no-load is
