Variable current resistor rX (Ω)
NOTE:
Ringing noise is produced in the current detection resistor
Rs when the MOSFET is switched ON and OFF through
chopping. This noise is also generated in feedback signals
from Rs which may therefore causes the comparator to
malfunction.
To prevent chopping malfunctions, r5(r6) and C3(C4) are
added in order to act as noise filter.
However, when the values of these constants are increased,
the response from Rs to the comparator becomes slow.
Hence, the value of the output current lo is higher to some
extent than the computed value.
