where ISMAX is max. current requested by the processor (see Intel docs for

details).

–

Adjust the defined values according to application bench tests.

–CSIMON in parallel to RSIMON can be added with proper time constant to prevent

false OC tripping.

Note:

This is the typical design flow. Custom design and specifications may require different

settings and ratios between the per-phase OC threshold and the total current OC threshold.

Applications with big ripple across inductors may be required to set per-phase OC to values

different than 110%: design flow should be modified accordingly.
