Introduction
The ADuM3470/ADuM3471/ADuM3472/ADuM3473/ADuM3474 devices are quad-channel digital isolators that integrate a PWM controller and transformer driver for driving isolated DC/DC converters. The DC/DC converter provides a regulated, isolated power supply of 2 W at 3.3 V to 24 V, with an input supply voltage of 5.0 V or 3.3 V. This eliminates the need for a separate isolated DC/DC converter in 2 W isolation designs. iCoupler chip-scale transformer technology is used for logic signal isolation; the integrated transformer driver with isolated secondary-side control improves the efficiency of the isolated DC/DC converter, thereby delivering a compact, fully isolated solution.
Features
- Isolated PWM controller
- Integrated transformer driver
- Adjustable regulated output: 3.3 V to 24 V
- 2 W output power
- Efficiency: 70% (at 400 mA guaranteed load, 5.0 V output)
- Four DC - 25 Mbps (NRZ) signal isolation channels
- 20-pin SSOP package
- Operating temperature up to 105°C
- High common-mode transient immunity: >25 kV/μs
- Adjustable oscillator frequency: 200 kHz to 1 MHz
- Soft-start at power-up
- Pulse-by-pulse overcurrent protection
- Thermal shutdown
- 2500 V rms isolation
Applications
- RS-232/RS-422/RS-485 transceivers
- Industrial fieldbus isolation
- Power supply startup biasing and gate driving
- Isolated sensor interfaces
- Process control
