Primary Supply Voltage 3.0V to 5.5 V. Pin 1 and Pin 7 are internally connected, and connecting both to V
recommended
Ground 1. Ground reference for converter Primary. Pin 2 and Pin 8 are internally connected, and it is recommended that
both pins be connected to a common ground.
No Internal Connection.
Regulation Control Input, In slave power configuration (RC
isoPower device, or tied low to disable the converter. In Master/Stand alone mode(RC
function. This pin is weakly pulled to low. In Noisy environments it should be tied to low or to a PWM control source.
Warning -This pin must not be tied high if RC
secondary, damaging the ADuM5000 and possibly devices that it powers.
Regulation Control Output, In master power configuration, this pin is connected to the RC
to allow the ADuM5000 to regulate additional devices.
Control input, Determines Master/self regulation (CTL High) mode or Slave mode(CTL Low)allowing external
regulation. This pin is weakly pulled to high. In noisy environments it should be tied either high or low.
Primary Supply Voltage 3.0V to 5.5 V. Pin 1 and Pin 7 are internally connected, and connecting both to V
recommended.
Ground reference for converter Secondary. Pin 9 and Pin 15 are internally connected, and it is recommended that both pins
be connected to a common ground.
Secondary Supply Voltage Output External Loads, 3.3V (VSEL Low) or 5.0V (VSEL High), 5.0V output Functioanlity not
guaranteed for a 3.3V primary supply input. Pin 10 and Pin 16 are internally connected, and connecting both to GND
recommended.
No Internal Connection.
No Internal Connection.
Output Voltage Selection: When V
is 3.3V. This pin is weakly pulled to high. In noisy environments it should be tied either high or low. In Slave regulation
mode this pin has no function.
No Internal Connection.
Secondary Supply Voltage Output External Loads, 3.3V (VSEL Low) or 5.0V (VSEL High), 5.0V output Functioanlity not
guaranteed for a 3.3V primary supply input. Pin 10 and Pin 16 are internally connected, and connecting both to GND
recommended.
