Frequency Select (FSEL1)
Sometimes it is necessary to operate the converter at a
lower switching frequency to keep the losses low for
lower power dissipation. However, it is not possible to
have different frequencies for two converters operating
out-of-phase. Also, frequency beating may occur if the
individual converter frequencies are not selected care-
fully. To avoid these issues, and still achieve the lower
power dissipation in the package, the MAX5072 pro-
vides a frequency select (FSEL1) pin. Connecting
FSEL1 to ground reduces the switching frequency of
converter 1 to 1/2 the switching frequency of converter
2 and 1/4th of the internal oscillator switching frequen-
cy. In this case, the input capacitor ripple frequency is
1.5 times the converter 2 switching frequency and also
has unsymmetrical ripple waveform.
