DRIVE2 (Pin 1)
Connect this pin to the gate of an external MOSFET.
This pin provides the drive for the AGP regulator’s
pass transistor.
FIX (Pin 2)
Grounding this pin bypasses the internal resistor di-
viders that set the output voltage of the 1.5V and 1.
8V linear regulators. This way, the output voltage of
the two regulators can be adjusted from 1.26V up to
the input voltage (+3.3V or +5V) by way of an exter-
nal resistor divider connected at the corresponding
VSEN pin. The new output voltage set by the exter-
nal resistor divider can be determined using the fol-
lowing formula:
VOUT =1.265V × [1+ROUT/ RGND ]
where R is the resistor connected from VSEN to
OUT
the output of the regulator, and R is the resistor
GND
connected from VSEN to ground. Left open, the FIX
pin is pulled high, enabling fixed output voltage
operation.
