Power Ground and Quiet Ground for Controller Circuits.
Switch Node.
Supply Voltage Input. The RT5796A operates from a 2.5V to 6V
unregulated input. C1 is needed to prevent large voltage spikes from
appearing at the input.

VIN
Quiet ground for controller circuits.
Feedback Voltage Input. An external resistor divider from the output to
GND, tapped to the FB pin, sets the output voltage.

Power Good Indicator. The output of this pin is an open-drain with
external pull-up resistor to IN. PG is pulled up to IN when the FB voltage
is within 90%, otherwise it is LOW.
