Based on the Analog Devices, Inc., i Coupler® technology, the dc-todc converter provides regulated, isolated power that is adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage binations and their associated power levels are shown in Table 1. The ADu M5210/ADu M5211/ADu M5212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The i Coupler chip-scale transformer technology is used for isolated logic signals and for the magnetic ponents of the dcto-dc converter. The result is a small form factor, total isolation solution. iso Power uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout remendations.
