FADC PCC Slope Compensation Circuit; Clarification Example
This circuit is a downsized version of the corresponding ACMP example in Figure 64. The RC-
network accomplishes external linear control of a slope compensation voltage ramp.

CCU 4 Blanking Control
There is a CCU 4 blanking control, to reject noise from power switch commutations, proposed by
using the Gate functionality of the VADC input channel.
Note: An alternative would be to use the corresponding function in the ACMP example in Figure 64
intead.
Current Measurement Signal
The output voltage of the Current Measurement is assumed to be representing the inductor current.
See section 7.2.
