VAUX (Pin 16)
Connect this pin to the ATX 3.3V output. The voltage present
at this pin is monitored for sequencing purposes. This pin
provides the necessary base bias for the NPN pass
transistors, as well as the current sunk through the 5k ? VID
pull-up resistors.
SS13 (Pin 13)
Connect a capacitor from this pin to ground. This capacitor,
along with an internal 28 μ A current source, sets the
soft-start interval of the synchronous switching converter

Functional Pin Descriptions
VCC (Pin 28)
Provide a 12V bias supply for the IC to this pin. This pin also
provides the gate bias charge for all the MOSFETs
controlled by the IC. The voltage at this pin is monitored for
Power-On Reset (POR) purposes.
GND (Pin 17)
Signal ground for the IC. All voltage levels are measured with
respect to this pin.

SS24 (Pin 12)
Connect a capacitor from this pin to ground. This capacitor,
along with an internal 28 μ A current source, sets the
soft-start interval of the standard buck converter. Pulling this
pin below 0.8V induces a chip reset (POR) and shutdown.
VTTPG (Pin 9)
VTTPG is an open collector output used to indicate the
status of the standard buck regulator output voltage. This pin
is pulled low when the output is below the under-voltage
threshold or when the SS13 pin is below 1.25V.
