13 Output voltage Monitor and Protections
The trans-conductance resistor R_ISENx can be designed considering that the device limits the
bottom of the inductor current ripple and also considering the additional current delivered
during the quasi-constant-current behavior as previously described in the worst case
conditions.
Moreover, when designing D-VID compatible systems, the additional current due to the output
filter charge during dynamic VID transitions must be considered.
