PGOOD DELAY
Connecting a capacitor between this pin and ground a delay is introduced
between the trigger of the internal PGOOD comparator and the external signal
rising edge. No delay can be introduced on the falling edge of the PGOOD
signal. The delay can be calculated with the following formula:
2
SYNCH
It is a Master-Slave pin. Two or more devices can be synchronized by simply
connecting the SYNCH pins together. The device operating with the highest
FSW will be the Master. The Slave devices will operate with 180° phase shift
from the Master. The best way to synchronize devices together is to set their
FSW at the same value. If it is not used the SYNCH pin can be left floating.

SINK/OVP/UVLO
L6730C
CC/OVP/UVLO
L6730D
With this pin it is possible:
– To enable-disable the sink mode current capability after SS (L6730C);
– To enable-disable the constant current OCP after SS (L6730D);
– To enable-disable the latch mode for the OVP;
– To set the UVLO threshold for the 5V BUS and 12V BUS.
The device captures the analog value present at this pin at the start-up when
VCC meets the UVLO threshold.
