Product Overview

The ADUM3471 series quad-channel Digital Isolator with an integrated PWM controller and transformer driver for an isolated DC-to-DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC-to-DC converter provides up to 2W of regulated, isolated power at 3.3 to 24V from a 5V input supply or from a 3.3V supply. This eliminates the need for a separate, isolated DC-to-DC converter in 2W isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and the integrated transformer driver with isolated secondary side control provides higher efficiency for the isolated DC-to-DC converter. The result is a small form factor, total isolation solution.
  • Isolated PWM controller
  • Integrated transformer driver
  • 2W Output power
  • Soft start function at power-up
  • Pulse-by-pulse overcurrent protection
  • Thermal shutdown
  • >25kV/µs High common-mode transient immunity
