Power Ground through a sensing power resistor.
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current
Controller OFF-Time.
Ground terminals. On PowerDIP24 and SO24
packages, these pins are also used for heat
dissipation toward the PCB. On PowerSO36 package
the slug is connected on these pins.
