Given the chip already has a current control mechanism, it's rather obvious that the correct approach is to work with that mechanism by changing VRef, and not to be slamming the whole thing on and off at a PWM duty cycle. If it's disabled, that should be because it's not needed for a meaningful period of time. | |
