I wonder if these ICs might close the gap between those cheap wall adapter power supplies, and the high-end types.

As the switch mode operation depends on a IC clock oscillator, the obvious question is what happens when a current surge or ESD discharge crashed the IC firmware and left the solid-state switches in closed state. Yes, the overcurrent protection would trip and prevent a fire, but it's still a failure if I'm powering an UPS with uncharged battery.

Maybe not for wall adapters yet.

@gonzalo060375 In theory the watchdog would reset the processor but I could easily see the time during reset being an issue...
