Pin Descriptions
VCC
The bias supply input for the small signal circuitry. Connect
this pin to the highest supply voltage available if two or more
options are available. Locally filter this pin using a quality
0.1
μF ceramic capacitor and 5Ω resistor (optional).
PVIN1, PVIN2, PVIN3, PVIN4, PVIN5, PVIN6
These pins are the power supply pins for the corresponding
PWM power blocks. Associated power blocks must all tie to
the same power supply. The power supply must fall in the
range of 2.375V to 5.5V.
GND
Signal ground. All small signal components connect to this
ground, which in turn connects to PGND at one point.
PGND
Power ground for the PWM power blocks and thermal relief
for the package. The exposed pad must be connected to
PGND and soldered to the PCB. Connect these pins closely
to the negative terminal of input and output capacitors.
FB1, FB2
Voltage feedback input. Depending on voltage selection pin
settings, connect an optional resistor divider between VOUT
and GND for selection of a variable output voltage.
LX1, LX2, LX3, LX4, LX5, LX6
Switch node connection to inductor. This pin connects to the
internal synchronous power MOSFET switches. The
average voltage of this node is equal to the regulator output
voltage.
