Product Detailed Description for ADUM3470
The ADuM3470/ADuM3471/ADuM3472/ADuM3473/ADuM3474 devices are quad-channel, digital isolators withan integrated PWM controller and transformer driver for anisolated DC/DC converter. Based on the Analog Devices, Inc.,iCoupler® technology, the DC/DC converter provides up to 2 Wof regulated, isolated power at 3.3 V to 24 V from a 5.0 V inputsupply or from a 3.3 V supply. This eliminates the need for aseparate, isolated DC/DC converter in 2 W isolated designs.The iCoupler chip-scale transformer technology is used to isolatethe logic signals, and the integrated transformer driver withisolated secondary side control provides higher efficiency for theisolated DC/DC converter. The result is a small form factor, totalisolation solution.
The ADuM347x isolators provide four independent isolationchannels in a variety of channel configurations and data rates.
Applications
- RS-232/RS-422/RS-485 transceivers
