provides the gate bias charge for
all the MOSFETs controlled by
the IC. Recommended supply
voltage is 12V.
Soft-start pin. Connect a capaci-
tor from this pin to ground. This
capacitor, along with an internal
10 A (typically) current source,
sets the soft-start interval of the
converter.
Pulling this pin low will shut down
the IC.
Connect this pin to a resistor d i-
vider to set the linear regulator
output voltage.
