for a coil current cycle in continuous mode. The average coil current is
equal to the average current demanded by the load. The lengths of t1 and t2 are
determined by the battery voltage and the output voltage of the DC-to-DC converter. The
output voltage is allowed to vary within a certain window. This means that there will be a
voltage ripple with a frequency that is largely correlated to the frequency content of the
load current. The peak-to-peak amplitude of the ripple will be more or less equal to the
window height. There will be ripple at the switching frequency too, this is mainly caused by
the fact that the coil current will run through parasitic resistances of the load circuit.
