1
V_DD1
2, 8 GND₁
Primary Supply Voltage, 3.0 V to 5.5 V.
Ground 1. Ground reference for isolator primary. Pin 2 and Pin 8 are internally connected, and it is recommended that
both pins be connected to a common ground.

7
RC_OUT
Regulation Control Output. This pin is connected to the RC_IN pin of a slave isoPower device to allow the ADuM5403 to
control the regulation of the slave device.
9, 15 GND_ISO
Ground Reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and it is recommended that both pins
be connected to a common ground.
