The implementation of the FVMC and FCMV modes can be combined with the use of a dual SPDT switch such as the TMUX6136. Figure 8-3 and Figure 8-4 shows simplified diagrams of such implementations. In the FVMC mode, the switch is toggled to position A and this allows the voltage sense amplifier to become part of the feedback loop and the voltage output of the current sense amplifier to be sampled by the ADC. In the FCMV mode, the switch is toggled to position B, and this allows the current sense amplifier to become part of the feedback loop and the voltage output of the voltage sense amplifier to be sampled by the ADC.
