Description
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 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.
Regulation Control Input. In slave power configuration (RC

this pin has no function. This pin is weakly pulled to the low state. In noisy environments, it should be tied low
or tied to a PWM control source. This pin must not be tied high if RC

Ground Reference for the Secondary Side of the Converter. Pin 9 and Pin 15 are internally connected to each
other, and it is recommended that both pins be connected to a common ground.
Secondary Supply Voltage Output for External Loads. 3.3 V (V
functionality is not guaranteed for a 3.3 V primary supply input. Pin 10 and Pin 16 are internally connected
to each other, and it is recommended that both pins be externally connected.
