I'm currently working the project that uses LTM4700. I checked the ripple noise on output voltage and got a high level of ripple (~2-300mV).
So, I tried to change value of MFR_PWM_COMP with the gm and RCOMP value from LTpowerCAD. The value of this byte is changed but I didn't see any improvements.
The datasheet said we can optimize the compensation loop by modifying these parameters. Am I understand correctly?
Is there anything I missed? Please advise.
- Typo fixed.
