PIN FUNCTIONS
V IN1 , V IN2 (J1-J6, K1-K6); (C1-C6, D1-D6): 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 (J9-J12, K9-K12, L9-L12, M9-M12); (C9-C12,
D9-D12, E9-E12, F9-F12): Power Output Pins. Apply out-
put load between these pins and GND pins. Recommend
placing output decoupling capacitance directly between
these pins and GND pins. Review Table 4.
GND1, GND2, (G1-G12, H1, H7-H12, J7-J8, K7-K8, L1,
L7-L8, M1-M8); (A1-A12, B1, B7-B12, C7-C8, D7-D8,
E1, E7-E8, F1-F8): 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.
