1, 7 VDD1 Primary Supply Voltage 3.0 V to 5.5 V. Pin 1 and Pin 7 are internally connected to each other, and it is recom- mended that both pins be externally connected to a common power source. 2, 8 GND1 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. 3, 11, 12, 14 NC No Internal Connection. 4 RCIN Regulation Control Input. In slave power configuration (RCSEL = low), this pin is connected to the RCOUT pin of a master isoPower device, or tied low to disable the converter. In master/standalone mode (RCSEL = high), this pin has no function. This pin is weakly pulled to low. In noisy environments, it should be tied to low or to a PWM control source. Note that this pin must not be tied high if RCSEL is low; this combination causes excessive voltage on the secondary side of the converter, damaging the ADuM5000W and possibly the devices that it powers. 5 RCOUT Regulation Control Output. In master power configuration, this pin is connected to the RCIN pin of a slave isoPower device to allow the ADuM5000W to regulate additional devices. 6 RCSEL Control Input. Sets either self-regulation/master mode (RCSEL high) or slave mode (RCSEL low). This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low. 9, 15 GNDISO 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. 10, 16 VISO Secondary Supply Voltage Output for External Loads, 3.3 V (VSEL low) or 5.0 V (VSEL high). 5.0 V output functionality is not guaranteed for a 3.3 V primary supply input. Pin 10 and Pin 16 are internally connected to each other and connecting both externally is recommended. 13 VSEL Output Voltage Selection. When VSEL = VISO, the VISO setpoint is 5.0 V. When VSEL = GNDISO, the VISO setpoint is 3.3 V. This pin is weakly pulled to high. In noisy environments, tie this pin either high or low. In slave regulation mode, this pin has no function.

L H H X X X Note that this combination of RCIN and RCSEL is prohibited. Damage occurs on the secondary side of the converter due to excess output voltage at VISO. RCIN must be low, or it must be connected to a PWM signal from a master isoPower part. 1 X = don’t care. 2 PWM refers to the regulation control signal. This signal is derived from the secondary side regulator or from the RCIN input, depending on the value of RCSEL. 3 VDD1 must be common between all isoPower devices being regulated by a master isoPower part.
