PIN FUNCTIONS
V IN1 , V IN2 (J1-J5, K1-K5); (C1-C6, D1-D5): Power Input
Pins. Apply input voltage between these pins and GND
pins. Recommend placing input decoupling capacitance
directly between V IN pins and GND pins.
V OUT1 , V OUT2 (K9-K12, L9-L12, M9-M12); (C9-C12,
D9-D12, E11-E12): Power Output Pins. Apply output load
between these pins and GND pins. Recommend placing
output decoupling capacitance directly between these pins
and GND pins. Review Table 4.
GND1, GND2, (H1, H7-H12, J6-J12, K6-K8 L1, L7-L8,
M1-M8); (A1-A12, B1, B7-B12, C7-C8, D6-D8, E1,
E8-E10): Power Ground Pins for Both Input and Output
Returns.
TRACK1, TRACK2 (L3, E3): Output Voltage Tracking Pins.
When the module is configured as a master output, then a
soft-start capacitor is placed on the RUN/SS pin to ground
to control the master ramp rate, or an external ramp can
be applied to the master regulator’s track pin to control it.
Slave operation is performed by putting a resistor divider
from the master output to ground, and connecting the
center point of the divider to this pin on the slave regulator.
If tracking is not desired, then connect the TRACK pin to
V IN . Load current must be present for tracking. See the
Applications Information section.
FB1, FB2 (L6, E6): The Negative Input of the Switching
Regulators’ Error Amplifier. Internally, these pins are con-
nected to V OUT with a 4.99k precision resistor. Different
output voltages can be programmed with an additional
resistor between the FB and GND pins. Two power modules
can current share when this pin is connected in parallel
with the adjacent module’s FB pin. See the Applications
Information section.
FB3 (F6): The Negative Input of the LDO Error Amplifier.
Internally the pin is connected to LDO_OUT with a 4.99k
resistor. Different output voltages can be programmed with
an additional resistor between the FB3 and GND pins. See
the Applications Information section.
COMP1, COMP2 (L5, E5): Current Control Threshold
and Error Amplifier Compensation Point. The current
comparator threshold increases with this control voltage.
Two power modules can current share when this pin is
connected in parallel with the adjacent module’s COMP
pin. Each channel has been internally compensated. See
the Applications Information section.
PGOOD1, PGOOD2 (L4, E4): Output Voltage Power
Good Indicator. Open-drain logic output that is pulled to
ground when the output voltage is not within ±7.5% of
the regulation point.
RUN/SS1, RUN/SS2 (L2, E2): Run Control and Soft-Start
Pin. A voltage above 0.8V will turn on the module, and
below 0.5V will turn off the module. This pin has a 1M
resistor to V IN and a 1000pF capacitor to GND. See the
Applications Information section for soft-start information.
SW1, SW2 (H2-H6, B2-B6): The switching node of the
circuit is used for testing purposes. This can be connected
to copper on the board for improved thermal performance.
SW1 and SW2 must be floating on separate copper planes.
LDO_IN (G1-G4): VLDO Input Power Pins. Place input
capacitor close to these pins.
LDO_OUT (G9-G12): VLDO Output Power Pins. Place
output capacitor close to these pins. Minimum 1mA load
is necessary for proper output voltage accuracy.
BOOST3 (E7): Boost Supply for Driving the Internal VLDO
NMOS Into Full Enhancement. The pin is use for testing
the internal boost converter. The output is typically 5V.
GND3 (F1-F5, F7, F9-F12, G6-G8): The power ground pins
for both input and output returns for the internal VLDO.
PGOOD3 (G5): VLDO Power Good Pin.
EN3 (F8): VLDO Enable Pin.
