Hello @chandraprakash ,

Thank you for contributing to the Infineon community.

TDA38640 IPOL (SVID) and TDA38740 IPOL (PMBus) has  a nominal accuracy of +/- 6% specified at a maximum load 

IMON for these is designed to meet the Intel IMON specification for VR14 which is part of the VR14 PWM specification sheet.

IMON  may be tuned to meet the accuracy goals for any current using the offset and gain correction in the PMBus domain.

Regards,

Nishanth
