PM6686
The section with the EN pin connected to VREF2 begins the soft-start only when the other
section is in regulation (its PGOOD is high) and makes a soft-end suddenly when the other
section is turned off.
Figure 53. VOUT2 behavior if EN2 is connected to VREF2
To protect the EN1, EN2, EN_LDO and SKIP pin of the PM6686 an external divider or a
series resistor is required, in order to prevent a large inrush current flowing into the device in
case the voltage spike is exceeding the recommended operating conditions.
