Figure 14. Virtual ESR network
The CDC capacitor decouples the feedback DC path through the RCOT so the output voltage
is adjusted accordingly with Section 4.1 on page 13.
Basically the network RCOT, CCOT generates a voltage signal proportional to the inductor
current ripple and superimposed with the real partitioned output voltage that increases the
SNR at the input of the PWM comparator. As a consequence the PWM converter
commutation is clean, removing the duty cycle dithering.
For the purpose of the signal generated by the RCOT and CCOT the output capacitor
represents a virtual ground so the equivalent small signal circuit of the output of the virtual
ESR network is shown in Figure 15.
