Comparator circuit with IC10 is designed as a non-inverting comparator. This setup, together with IC11 flip-flop, works as a minimal power limiter. It should be used as an inverting comparator, so the OP-AMP's output is driven LOW (disables output power), when RF_VRMS voltage exceeds threshold voltage.
