When hiccup overload mode is detected on the slave
channel only, the output voltage of the 2nd channel (slave)
decreases. After the overload condition ends, the slave
channel voltage remains low. If the slave channel should rise

For proper operation of the modified tracking mode, use
an SS1 capacitor with a value at least 10 times higher than
that of the SS2 capacitor.
