TPS65217: TPS65217C

Are pins 24 and 29  DCDC2[3} output/feedback voltage sense input really an output per the data sheet?

Pin 19  DCDC2 output/feedback voltage sense input is marked as an Input.

    I do not understand the question: all pins are listed with identical wording in the datasheet.

    These pins are all inputs to the PMIC.

    The switching nodes of the DCDC converters are L1 (pin 20), L2 (pin 23), L3 (pin 31) and is where the high current flows out. These are listed as outputs.

    The VDCDCx nets are outputs of the system in that this is the net where the load will connect (thick trace, or polygon pour, for high current).

    The VDCDCx pins are inputs to the PMIC in that this is where the sense line connects back to the device (thin trace, or Kelvin connection, for low current).
