Primary Supply Voltage 3.0 V to 5.5 V. Pin 1 and Pin 7 are internally connected to each other, and it is recommended
that both pins be externally connected to a common power source.
Ground 1. Ground reference for the primary side of the converter. Pin 2 and Pin 8 are internally connected to each other,
and it is recommended that both pins be connected to a common ground.
No Internal Connection.
