Product Details

ADuM347x Isolated Switching Regulators, Analog Devices

The ADuM347x series from Analog Devices are a range of quad channel digital isolators incorporating Analog Devices’ iCoupler® technology with an integrated PWM controller and transformer driver. This design eliminates the need for a separate isolated DC-to-DC converter in 2W isolated designs.


Isolated PWM controller
Integrated transformer driver
Regulated adjustable output: 3.3V to 24V
2W output power
70% efficiency at guaranteed load of 400mA at 5.0V output
Quad DC-to-25Mbps signal isolation channels
High common-mode transient immunity: >25kV/μs
200kHz to 1MHz adjustable oscillator frequency
Soft start function at power-up
Pulse-by-pulse overcurrent protection
Thermal shutdown
3.3V to 5V input logic
4.5V to 18V output drive
Thermal shutdown protection at >150°C
2500Vrms isolation voltage

Typical Applications

RS-232/RS-422/RS-485 transceivers
Industrial field bus isolation
Power supply start-up bias and gate drives
Isolated sensor interfaces
Process controls
