FB (E7): The Negative Input of the Error Amplifier. Internally,
this pin is connected to V
Different output voltages can be programmed with an ad-
ditional resistor between FB and GND pins. In PolyPhase
operation, tie FB pins together for parallel operation. See
the Applications Information section for details.
I
Compensation Point. The current comparator threshold
increases with this control voltage. Tie together in parallel
operation.
I
Amplifier. Tie this pin to SGND for single phase operation.
For PolyPhase operation, tie the master’s I

PGOOD (C7): Output Voltage Power Good Indicator.
Open-drain logic output that is pulled to ground when the
output voltage is not within ±10% of the regulation point.
Disabled during margining.
RUN (F1): Run Control Pin. A voltage above 1.5V will turn
on the module.
SW (C3-C5): Switching Node of the Circuit is Used for
Testing Purposes. This can be connected to an electri-
cally open circuit copper pad on the board for improved
thermal performance.
CLKOUT (F2): Output Clock Signal for PolyPhase Opera-
tion. The phase of CLKOUT is determined by the state of
the PHMODE pin.
