Equation 3
Where Ip(VCOMPbl
2) is the peak Power MOSFET current corresponding to a compensation
voltage of VCOMPbl (1V).
Note:
The power point PSTBY where the converter is going into burst mode does not depend on
the input voltage.
The standby frequency FSWstby is given by:
Equation 4
The ratio between the nominal and standby switching frequencies can be as high as 4,
depending on the Lp value and input voltage.
