3 Based on the analog devices , Inc., iCoupler technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power at either V or V from a V input supply, or V from a V supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and for the magnetic components of the dc-to-dc converter . The result is a small form factor, total isolation solution. The adum5200 / adum5201 / adum5202 Isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information).

4 IsoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.
