provide two independent isolation channels in a variety of channel 5.0 5.0 400 configurations and data rates (see the Ordering Guide for more 5.0 3.3 330 information). 3.3 3.3 122 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.
