Soft start
L6714 implements a soft-start to smoothly charge the output filter avoiding high in-rush
currents to be required to the input power supply. The device increases the reference from
zero up to the programmed value in different ways according to the selected Operative
Mode and the output voltage increases accordingly with closed loop regulation.
The device implements Soft-Start only when all the power supplies are above their own turn-
on thresholds and the OUTEN pin is set free.
At the end of the digital Soft-Start, SS_END/PGOOD signal is set free. Protections are
active during this phase; Under Voltage is enabled when the reference voltage reaches 0.6V
while Over Voltage is always enabled with a threshold dependent on the selected Operative
Mode or with the fixed threshold programmed by ROVP (See “Over voltage and
