Inductor DCR Temperature Correction
If the thermal compensation of the inductor DCR provided by the temperature dependent gain of the current sense
amplifier is not adequate, a negative temperature coefficient (NTC) thermistor can be used for additional correction.
The thermistor should be placed close to the inductor and connected in parallel with the feedback resistor, as
shown in Figure 9. The resistor in series with the thermistor is used to reduce the nonlinearity of the thermistor. A
similar network must be placed on the BBFB pin to ensure proper operation during a transition to a lower VID code
with Body Braking

Remote Voltage Sensing
To reduce the effect of impedance in the ground plane, the VOSNS- pin is used for remote sensing and connected
directly to the load. The VDAC voltage is referenced to VOSNS- to avoid additional error terms or delay related to a
separate differential amplifier. The capacitor connecting the VDAC and VOSNS- pins ensure that high speed
transients are fed directly into the error amplifier without delay.
