PGND
SGND
Power Ground. Provides the ground return path for the high-side drive current.
Signal (Analog) Ground. Provides return path for control circuitry and internal
reference.

BIAS
Internal circuit bias supply. Must be bypassed with a 0.1μF ceramic capacitor to
SGND.

FB
Feedback. Input to the error amplifier, connect to the external resistor divider network
to set the output voltage.
