How does DNA series regulate temperature?

[Rivas]

what happens after the specified temperature is reached? does it just shut down the power supply so I need to refire or what?

It modulates the wattage up or down to maintain the set temperature, so it will continue to fire as long as the button is held down, but if conditions aren't right (ie proper airflow/wicking) it will likely be firing at VERY low wattage to maintain the set temp.

it throttles the power down to stay at the right temperature and not get too hot.

It ramps up at full power set, once the resistance reaches approximately where a given temperature is set at, it begin to Pulse Width Modulate voltage to maintain temperature, check pbusardo's on youtube videos on the DNA40 and SX Mini M to see how the power signals drop and pulse once temp throttle kicks in.

DNA's (and all Evolv chips) do not use PWN, its a flat DC-DC signal, though i can see how what the chip does could be viewed as a form of pulse width modulation.

Yihi's chips do use a form of PWN for the temp control but its still different than the PWN that we were used to back in the "rattlesnake" 33hz chip days.
