Operating modes
Turn-on
When the input voltage is applied, the Enable/Fault pin goes up to the high state, enabling
the internal control circuitry.
After an initial delay time of typically 500 µs, the output voltage is supplied with a slope
defined by the internal dv/dt circuitry. If no additional capacitor is connected to dv/dt pin, the
total time from the Enable signal going high and the output voltage reaching the nominal
value is around 1 ms (refer to
