These pins switch ON at High level and OFF at Low level. They
serve as power-supply pins for the DC/DC converter to generate the
switch gate voltage.
Switch Input pins: Two common pins are assigned to SWIN
SWIN
which starts at 1.5 V Min.
Switch output pins: Two common pins are assigned to SWOUT
and SWOUT
charge circuit starts discharge via these pins.
SWOUT
used to discharge from the load-side capacitor at switch OFF.
Connect them to GND when discharge is not required.
Switch-ON/OFF control pins: The ON/OFF time can be delayed
by connecting an external capacitor. Both times are delayed about
three fold by installing a 500-pF capacitor between these pins and
GND. Leave these pins open when they are not used. 10 V may be
generated when these pins are open. To keep these pins at high
impedance, take care to mount the device so that no current leaks
(less than 0.1 A).
Ground pins for input threshold reference voltage and load
discharge: When two switching circuits are used, ground both
GND pins.
