What the delay times mean for your rail
The 10 µs turn-on delay is fast enough to catch a sagging rail before the downstream converter browns out, but slow enough to avoid false triggering on load transients. The 200 µs turn-off delay gives the failing rail time to decay gracefully, preventing the good rail from back-feeding into a short. If you're sizing hold-up capacitors, the off-delay sets the window the output must stay within spec before the FET opens—tighten the cap bank if your load pulls hard during that 200 µs.
