I have a question about my Schmitt-Trigger boost converter design. In a conventional Schmitt Trigger design built around comparators, there is a positive feedback network, with the input voltage connected to the bottom of the divider. My question is whether the feedback network can be connected to the negative input of the comparator for an inverted output. (I would rather avoid adding a hex-inverter chip when I'll only use just one.)

The thread for my boost converter is here:
