How does the output of VCTRL relate to the CC and CV set?

  • Hi.

    VCTRL output pin is buffered VINT that is clamped to VCLP and VCLN input voltages such that:

    VVCLN − 0.5 V < VVCTRL < VVCLP + 0.5 V .

    VINT is coupled to the outputs of the CC and CV loop filter amplifiers via an analog NOR circuit or minimum output selector circuit. This means that the loop amplifier with the lowest output voltage is in control of VINT. The transfer function of the CC and CV loops will depend on your chosen external components and active amplifier configuration.
